Quotas and limits

This document lists the quotas and limits that apply to BigQuery.

A quota restricts how much of a shared Google Cloud resource your Google Cloud project can use, including hardware, software, and network components. Therefore, quotas are a part of a system that does the following:

  • Monitors your use or consumption of Google Cloud products and services.
  • Restricts your consumption of those resources, for reasons that include ensuring fairness and reducing spikes in usage.
  • Maintains configurations that automatically enforce prescribed restrictions.
  • Provides a means to request or make changes to the quota.

In most cases, when a quota is exceeded, the system immediately blocks access to the relevant Google resource, and the task that you're trying to perform fails. In most cases, quotas apply to each Google Cloud project and are shared across all applications and IP addresses that use that Google Cloud project.

There are also limits on BigQuery resources. These limits are unrelated to the quota system. Limits cannot be changed unless otherwise stated.

By default, BigQuery quotas and limits apply on a per-project basis. Quotas and limits that apply on a different basis are indicated as such; for example, the maximum number of columns per table, or the maximum number of concurrent API requests per user. Specific policies vary depending on resource availability, user profile, Service Usage history, and other factors, and are subject to change without notice.

Quota replenishment

Daily quotas are replenished at regular intervals throughout the day, reflecting their intent to guide rate limiting behaviors. Intermittent refresh is also done to avoid long disruptions when quota is exhausted. More quota is typically made available within minutes rather than globally replenished once daily.

Request a quota increase

To increase or decrease most quotas, use the Google Cloud console. For more information, see Request a higher quota.

For step-by-step guidance through the process of requesting a quota increase in Google Cloud console, click Guide me:

Cap quota usage

To learn how you can limit usage of a particular resource by specifying a smaller quota than the default, see Capping usage.

Required permissions

To view and update your BigQuery quotas in the Google Cloud console, you need the same permissions as for any Google Cloud quota. For more information, see Google Cloud quota permissions.

Troubleshoot

For information about troubleshooting errors related to quotas and limits, see Troubleshooting BigQuery quota errors.

Jobs

Quotas and limits apply to jobs that BigQuery runs on your behalf whether they are run by using Google Cloud console, the bq command-line tool, or programmatically using the REST API or client libraries.

Query jobs

The following quotas apply to query jobs created automatically by running interactive queries, scheduled queries, and jobs submitted by using the jobs.query and query-type jobs.insert API methods:

Quota Default Notes
Query usage per day Unlimited There is no limit to the number of bytes that can be processed by queries in a project.
View quota in Google Cloud console
Query usage per day per user Unlimited There is no limit to the number of bytes that a user's queries can process each day.
View quota in Google Cloud console
Cloud SQL federated query cross-region bytes per day 1 TB If the BigQuery query processing location and the Cloud SQL instance location are different, then your query is a cross-region query. Your project can run up to 1 TB in cross-region queries per day. See Cloud SQL federated queries.

This limit includes both interactive and batch queries. Interactive queries that contain UDFs also count toward the concurrent limit for interactive queries. This limit does not apply to GoogleSQL queries.
Daily query size limit Unlimited By default, there is no daily query size limit. However, you can set limits on the amount of data users can query by creating custom quotas to control query usage per day or query usage per day per user.
Daily destination table update limit See Maximum number of table operations per day. Updates to destination tables in a query job count toward the limit on the maximum number of table operations per day for the destination tables. Destination table updates include append and overwrite operations that are performed by queries that you run by using the Google Cloud console, using the bq command-line tool, or calling the jobs.query and query-type jobs.insert API methods.
Query/multi-statement query execution-time limit 6 hours

A query or multi-statement query can execute for up to 6 hours, and then it fails. However, sometimes queries are retried. A query can be tried up to three times, and each attempt can run for up to 6 hours. As a result, it's possible for a query to have a total runtime of more than 6 hours.

CREATE MODEL job timeout defaults to 24 hours, with the exception of time series, AutoML, and hyperparameter tuning jobs which timeout at 72 hours.

Maximum number of resources referenced per query 1,000 resources A query can reference up to 1,000 total of unique tables, unique views, unique user-defined functions (UDFs), and unique table functions after full expansion. This limit includes the following:
  • Tables, views, UDFs, and table functions directly referenced by the query.
  • Tables, views, UDFs, and table functions referenced by other views/UDFs/table functions referenced in the query.
Maximum unresolved legacy SQL query length 256 KB An unresolved legacy SQL query can be up to 256 KB long. If your query is longer, you receive the following error: The query is too large. To stay within this limit, consider replacing large arrays or lists with query parameters.
Maximum unresolved GoogleSQL query length 1 MB An unresolved GoogleSQL query can be up to 1 MB long. If your query is longer, you receive the following error: The query is too large. To stay within this limit, consider replacing large arrays or lists with query parameters.
Maximum resolved legacy and GoogleSQL query length 12 MB The limit on resolved query length includes the length of all views and wildcard tables referenced by the query.
Maximum number of GoogleSQL query parameters 10,000 parameters A GoogleSQL query can have up to 10,000 parameters.
Maximum request size 10 MB The request size can be up to 10 MB, including additional properties like query parameters.
Maximum response size 10 GB compressed Sizes vary depending on compression ratios for the data. The actual response size might be significantly larger than 10 GB. The maximum response size is unlimited when writing large query results to a destination table.
Maximum row size 100 MB The maximum row size is approximate, because the limit is based on the internal representation of row data. The maximum row size limit is enforced during certain stages of query job execution.
Maximum columns in a table, query result, or view definition 10,000 columns A table, query result, or view definition can have up to 10,000 columns.
Maximum concurrent slots for on-demand pricing 2,000 slots With on-demand pricing, your project can have up to 2,000 concurrent slots. BigQuery slots are shared among all queries in a single project. BigQuery might burst beyond this limit to accelerate your queries. To check how many slots you're using, see Monitoring BigQuery using Cloud Monitoring.
Maximum CPU usage per scanned data for on-demand pricing 256 CPU seconds per MiB scanned With on-demand pricing, your query can use up to approximately 256 CPU seconds per MiB of scanned data. If your query is too CPU-intensive for the amount of data being processed, the query fails with a billingTierLimitExceeded error. For more information, see billingTierLimitExceeded.
Multi-statement transaction table mutations 100 tables A transaction can mutate data in at most 100 tables.
Multi-statement transaction partition modifications 100,000 partition modifications A transaction can perform at most 100,000 partition modifications.
BigQuery Omni maximum query result size 20 GiB uncompressed The maximum result size is 20 GiB logical bytes when querying Azure or AWS data. If your query result is larger than 20 GiB, consider exporting the results to Amazon S3 or Blob Storage. For more information, see BigQuery Omni Limitations.
BigQuery Omni total query result size per day 1 TB The total query result sizes for a project is 1 TB per day. For more information, see BigQuery Omni limitations.
BigQuery Omni maximum row size 10 MiB The maximum row size is 10 MiB when querying Azure or AWS data. For more information, see BigQuery Omni Limitations.

Although scheduled queries use features of the BigQuery Data Transfer Service, scheduled queries are not transfers, and are not subject to load job limits.

Export jobs

The following limits apply to jobs that export data from BigQuery by using the bq command-line tool, Google Cloud console, or the export-type jobs.insert API method.

Limit Default Notes
Maximum number of exported bytes per day 50 TB You can export up to 50 TB(Tebibytes) of data per day from a project for free using the shared slot pool. You can set up a Cloud Monitoring alert policy that provides notification of the number of bytes exported. To export more than 50 TB(Tebibytes) of data per day, do one of the following:
Maximum number of export jobs per day 100,000 exports You can run up to 100,000 exports per day in a project. To run more than 100,000 exports per day, do one of the following:

BigQuery Data Transfer Service load job quota considerations

Load jobs created by BigQuery Data Transfer Service transfers are included in BigQuery's quotas on load jobs. It's important to consider how many transfers you enable in each project to prevent transfers and other load jobs from producing quotaExceeded errors.

You can use the following equation to estimate how many load jobs are required by your transfers:

Number of daily jobs = Number of transfers x Number of tables x Schedule frequency x Refresh window

Where:

  • Number of transfers is the number of transfer configurations you enable in your project.
  • Number of tables is the number of tables created by each specific transfer type. The number of tables varies by transfer type:

    • Campaign Manager transfers create approximately 25 tables.
    • Google Ads transfers create approximately 60 tables.
    • Google Ad Manager transfers create approximately 40 tables.
    • Google Play transfers create approximately 25 tables.
    • Search Ads 360 transfers create approximately 50 tables.
    • YouTube transfers create approximately 50 tables.
  • Schedule frequency describes how often the transfer runs. Transfer run schedules are provided for each transfer type:

  • Refresh window is the number of days to include in the data transfer. If you enter 1, there is no daily backfill.

Copy jobs

The following limits apply to BigQuery jobs for copying tables, including jobs that create a copy, clone, or snapshot of a standard table, table clone, or table snapshot. The limits apply to jobs created by using the Google Cloud console, the bq command-line tool, or the copy-type jobs.insert method. Copy jobs count toward these limits whether they succeed or fail.

Limit Default Notes
Copy jobs per destination table per day See Table operations per day.
Copy jobs per day 100,000 jobs Your project can run up to 100,000 copy jobs per day.
Cross-region copy jobs per destination table per day 100 jobs Your project can run up to 100 cross-region copy jobs for a destination table per day.
Cross-region copy jobs per day 2,000 jobs Your project can run up to 2,000 cross-region copy jobs per day.
Number of source tables to copy 1,200 source tables You can copy from up to 1,200 source tables per copy job.

For information on viewing your current copy job usage, see Copy jobs - View current quota usage.

The following limits apply to copying datasets:

Limit Default Notes
Maximum number of tables in the source dataset 20,000 tables A source dataset can have up to 20,000 tables.
Maximum number of tables that can be copied per run to a destination dataset in the same region 20,000 tables Your project can copy 20,000 tables per run to a destination dataset that is in the same region.
Maximum number of tables that can be copied per run to a destination dataset in a different region 1,000 tables Your project can copy 1,000 tables per run to a destination dataset that is in a different region. For example, if you configure a cross-region copy of a dataset with 8,000 tables in it, then BigQuery Data Transfer Service automatically creates eight runs in a sequential manner. The first run copies 1,000 tables. Twenty-four hours later, the second run copies 1,000 tables. This process continues until all tables in the dataset are copied, up to the maximum of 20,000 tables per dataset.

Standard tables

The following limits apply to BigQuery standard (built-in) tables:

Limit Default Notes
Table modifications per day 1,500 modifications

Your project can make up to 1,500 table modifications per table per day, whether the modification appends data, updates data, or truncates the table. This limit cannot be changed and includes the combined total of all load jobs, copy jobs, and query jobs that append to or overwrite a destination table.

DML statements do not count toward the number of table modifications per day.

Maximum rate of table metadata update operations per table 5 operations per 10 seconds Your project can make up to five table metadata update operations per 10 seconds per table. This limit applies to all table metadata update operations, performed by the following: This limit also includes the combined total of all load jobs, copy jobs, and query jobs that append to or overwrite a destination table or that use a DML DELETE, INSERT, MERGE, TRUNCATE TABLE, or UPDATE statements to write data to a table. Note that while DML statements count toward this limit, they are not subject to it if it is reached. DML operations have dedicated rate limits.

If you exceed this limit, you get an error message like Exceeded rate limits: too many table update operations for this table. This error is transient; you can retry with an exponential backoff.

To identify the operations that count toward this limit, you can Inspect your logs. Refer to Troubleshoot quota errors for guidance on diagnosing and resolving this error.

Maximum number of columns per table 10,000 columns Each table, query result, or view definition can have up to 10,000 columns.

External tables

The following limits apply to BigQuery tables with data stored on Cloud Storage in Parquet, ORC, Avro, CSV, or JSON format:

Limit Default Notes
Maximum number of source URIs per external table 10,000 URIs Each external table can have up to 10,000 source URIs.
Maximum number of files per external table 10,000,000 files An external table can have up to 10 million files, including all files matching all wildcard URIs.
Maximum size of stored data on Cloud Storage per external table 600 TB An external table can have up to 600 terabytes across all input files. This limit applies to the file sizes as stored on Cloud Storage; this size is not the same as the size used in the query pricing formula. For externally partitioned tables, the limit is applied after partition pruning.
Maximum number of files in the source Cloud Storage bucket Approximately 60,000,000 files An external table can reference a Cloud Storage bucket containing up to approximately 60,000,000 files. For externally partitioned tables, this limit is applied before partition pruning.

Partitioned tables

The following limits apply to BigQuery partitioned tables.

Partition limits apply to the combined total of all load jobs, copy jobs, and query jobs that append to or overwrite a destination partition.

A single job can affect multiple partitions. For example, query jobs and load jobs can write to multiple partitions.

BigQuery uses the number of partitions affected by a job when determining how much of the limit the job consumes. Streaming inserts do not affect this limit.

For information about strategies to stay within the limits for partitioned tables, see Troubleshooting quota errors.

Limit Default Notes
Number of partitions per partitioned table 4,000 partitions Each partitioned table can have up to 4,000 partitions. If you exceed this limit, consider using clustering in addition to, or instead of, partitioning.
Number of partitions modified by a single job 4,000 partitions Each job operation (query or load) can affect up to 4,000 partitions. BigQuery rejects any query or load job that attempts to modify more than 4,000 partitions.
Number of partition modifications per ingestion-time partitioned table per day 5,000 modifications

Your project can make up to 5,000 partition modifications per day, whether the modification appends data, updates data, or truncates an ingestion-time partitioned table.

The following limits apply to BigQuery table clones:

Limit Default Notes
Maximum number of clones and snapshots in a chain 3 table clones or snapshots Clones and snapshots in combination are limited to a depth of 3. When you clone or snapshot a base table, you can clone or snapshot the result only two more times; attempting to clone or snapshot the result a third time results in an error. For example, you can create clone A of the base table, create snapshot B of clone A, and create clone C of snapshot B. To make additional duplicates of the third-level clone or snapshot, use a copy operation instead.
Maximum number of clones and snapshots for a base table 1,000 table clones or snapshots You can have no more than 1,000 existing clones and snapshots combined of a given base table. For example, if you have 600 snapshots and 400 clones, you reach the limit.

This quota applies to the project that contains the table being read. Other APIs including jobs.getQueryResults and fetching results from jobs.query and jobs.insert can also consume this quota.
View quota in Google Cloud console

The BigQuery Storage Read API can sustain significantly higher throughput than tabledata.list. If you need more throughput than allowed under this quota, consider using the BigQuery Storage Read API.

The following limits apply to BigQuery API (core) requests:

Limit Default Notes
Maximum number of API requests per second per user per method 100 requests A user can make up to 100 API requests per second to an API method. If a user makes more than 100 requests per second to a method, then throttling can occur. This limit does not apply to streaming inserts.
Maximum number of concurrent API requests per user 300 requests If a user makes more than 300 concurrent requests, throttling can occur. This limit does not apply to streaming inserts.
Maximum request header size 16 KiB Your BigQuery API request can be up to 16 KiB, including the request URL and all headers. This limit does not apply to the request body, such as in a POST request.
Maximum jobs.get requests per second 1,000 requests Your project can make up to 1,000 jobs.get requests per second.
Maximum jobs.query response size 20 MB By default, there is no maximum row count for the number of rows of data returned by jobs.query per page of results. However, you are limited to the 20-MB maximum response size. You can alter the number of rows to return by using the maxResults parameter.
Maximum jobs.getQueryResults row size 20 MB The maximum row size is approximate because the limit is based on the internal representation of row data. The limit is enforced during transcoding.
Maximum projects.list requests per second 2 requests Your project can make up to two projects.list requests per second.
Maximum number of tabledata.list requests per second 1,000 requests Your project can make up to 1,000 tabledata.list requests per second.

Maximum concurrent connections 2,000 in multi-regions; 400 in regions You can open a maximum of 2,000 concurrent ReadRows connections per project in the us and eu multi-regions, and 400 concurrent ReadRows connections in other regions. In some cases you may be limited to fewer concurrent connections than this limit.

Storage Write API

The following quotas apply to Storage Write API requests. The following quotas can be applied at the folder level. These quotas are then aggregated and shared across all child projects. To enable this configuration, contact Cloud Customer Care.

If you plan to request a higher quota limit, include the quota error message in your request to expedite processing.

Quota Default Notes
Concurrent connections 1,000 in a region; 10,000 in a multi-region

The concurrent connections quota is based on the client project that initiates the Storage Write API request, not the project containing the BigQuery dataset resource. The initiating project is the project associated with the API key or the service account.

Your project can operate on 1,000 concurrent connections in a region, or 10,000 concurrent connections in the US and EU multi-regions.

When you use the default stream in Java or Go, we recommend using Storage Write API multiplexing to write to multiple destination tables with shared connections in order to reduce the number of overall connections that are needed.

View quota in Google Cloud console

You can view usage quota and limits metrics for your projects in Cloud Monitoring. Select the concurrent connections limit name based on your region. The options are ConcurrentWriteConnectionsPerProject, ConcurrentWriteConnectionsPerProjectEU, and ConcurrentWriteConnectionsPerProjectRegion for us, eu, and other regions, respectively.

It is strongly recommended that you set up alerts to monitor your quota usage and limits. In addition, if your traffic patterns experience spikes and/or regular organic growth, it might be beneficial to consider over-provisioning your quota by 25 - 50% in order to handle unexpected demand.

Throughput 3 GB per second throughput in multi-regions; 300 MB per second in regions You can stream up to 3 GBps in the us and eu multi-regions, and 300 MBps in other regions per project.
View quota in Google Cloud console

You can view usage quota and limits metrics for your projects in Cloud Monitoring. Select the throughput limit name based on your region. The options are AppendBytesThroughputPerProject, AppendBytesThroughputPerProjectEU, and AppendBytesThroughputPerProjectRegion for us, eu, and other regions, respectively. Write throughput quota is metered based on the project where the target dataset resides, not the client project.

It is strongly recommended that you set up alerts to monitor your quota usage and limits. In addition, if your traffic patterns experience spikes and/or regular organic growth, it might be beneficial to consider over-provisioning your quota by 25 - 50% in order to handle unexpected demand.


CreateWriteStream requests 10,000 streams every hour, per project per region You can call CreateWriteStream up to 10,000 times per hour per project per region. Consider using the default stream if you don't need exactly-once semantics. This quota is per hour but the metric shown in the Google Cloud console is per minute.
Pending stream bytes 10 TB in multi-regions; 1 TB in regions For every commit that you trigger, you can commit up to 10 TB in the us and eu multi-regions, and 1 TB in other regions. There is no quota reporting on this quota.

The following limits apply to Storage Write API requests:

Limit Default Notes
Batch commits 10,000 streams per table You can commit up to 10,000 streams in each BatchCommitWriteStream call.
AppendRows request size 10 MB The maximum request size is 10 MB.

Streaming inserts

The following quotas and limits apply when you stream data into BigQuery by using the legacy streaming API. For information about strategies to stay within these limits, see Troubleshooting quota errors. If you exceed these quotas, you get quotaExceeded errors.

Limit Default Notes
Maximum bytes per second per project in the us and eu multi-regions 1 GB per second

Your project can stream up to 1 GB per second. This quota is cumulative within a given multi-region. In other words, the sum of bytes per second streamed to all tables for a given project within a multi-region is limited to 1 GB.

Exceeding this limit causes quotaExceeded errors.

If necessary, you can request a quota increase by contacting Cloud Customer Care. Request any increase as early as possible, at minimum two weeks before you need it. Quota increase takes time to become available, especially in the case of a significant increase.

Maximum bytes per second per project in all other locations 300 MB per second

Your project can stream up to 300 MB per second in all locations except the us and eu multi-regions. This quota is cumulative within a given multi-region. In other words, the sum of bytes per second streamed to all tables for a given project within a region is limited to 300 MB.

Exceeding this limit causes quotaExceeded errors.

If necessary, you can request a quota increase by contacting Cloud Customer Care. Request any increase as early as possible, at minimum two weeks before you need it. Quota increase takes time to become available, especially in the case of a significant increase.

Maximum row size 10 MB Exceeding this value causes invalid errors.
HTTP request size limit 10 MB

Exceeding this value causes invalid errors.

Internally the request is translated from HTTP JSON into an internal data structure. The translated data structure has its own enforced size limit. It's hard to predict the size of the resulting internal data structure, but if you keep your HTTP requests to 10 MB or less, the chance of hitting the internal limit is low.

Maximum rows per request 50,000 rows A maximum of 500 rows is recommended. Batching can increase performance and throughput to a point, but at the cost of per-request latency. Too few rows per request and the overhead of each request can make ingestion inefficient. Too many rows per request and the throughput can drop. Experiment with representative data (schema and data sizes) to determine the ideal batch size for your data.
insertId field length 128 characters Exceeding this value causes invalid errors.

For additional streaming quota, see Request a quota increase.
