A BigQuery destination.

Attributes

Name	Description
dataset	str Required. The BigQuery dataset in format "projects/projectId/datasets/datasetId", to which the analysis results should be exported. If this dataset does not exist, the export call will return an INVALID_ARGUMENT error.
table_prefix	str Required. The prefix of the BigQuery tables to which the analysis results will be written. Tables will be created based on this table_prefix if not exist: -
partition_key	google.cloud.asset_v1.types.IamPolicyAnalysisOutputConfig.BigQueryDestination.PartitionKey The partition key for BigQuery partitioned table.
write_disposition	str Optional. Specifies the action that occurs if the destination table or partition already exists. The following values are supported: - WRITE_TRUNCATE: If the table or partition already exists, BigQuery overwrites the entire table or all the partitions data. - WRITE_APPEND: If the table or partition already exists, BigQuery appends the data to the table or the latest partition. - WRITE_EMPTY: If the table already exists and contains data, an error is returned. The default value is WRITE_APPEND. Each action is atomic and only occurs if BigQuery is able to complete the job successfully. Details are at https://cloud.google.com/bigquery/docs/loading-data-local#appending_to_or_overwriting_a_table_using_a_local_file.

PartitionKey

PartitionKey(value)

This enum determines the partition key column for the bigquery tables. Partitioning can improve query performance and reduce query cost by filtering partitions. Refer to https://cloud.google.com/bigquery/docs/partitioned-tables for details.
