A client for BigQuery – A fully managed, petabyte scale, low cost enterprise data warehouse for analytics.
A simple usage example showing how to create a table in Bigquery. For the complete source code see CreateTable.java.
BigQuery bigquery = BigQueryOptions.getDefaultInstance().getService(); *
TableId tableId = TableId.of(datasetName, tableName);

Classes
Acl
Access Control for a BigQuery Dataset. BigQuery uses ACLs to manage permissions on datasets. ACLs are not directly supported on tables. A table inherits its ACL from the dataset that contains it. Project roles affect your ability to run jobs or manage the project, while dataset roles affect how you can access or modify the data inside a project. See Also: Access Control
Acl.DatasetAclEntity
Class for a BigQuery DatasetAclEntity ACL entity. Objects of this class represent a DatasetAclEntity from a different DatasetAclEntity to grant access to. Only views are supported for now. The role field is not required when this field is set. If that DatasetAclEntity is deleted and re-created, its access needs to be granted again via an update operation.
Acl.Domain
Class for a BigQuery Domain entity. Objects of this class represent a domain to grant access to. Any users signed in with the domain specified will be granted the specified access.
Acl.Entity
Base class for BigQuery entities that can be grant access to the dataset.
Acl.Group
Class for a BigQuery Group entity. Objects of this class represent a group to granted access to. A Group entity can be created given the group's email or can be a special group: #ofProjectOwners(), #ofProjectReaders(), #ofProjectWriters() or #ofAllAuthenticatedUsers().
Acl.IamMember
Class for a BigQuery IamMember entity. Objects of this class represent a iamMember to grant access to given the IAM Policy.
Acl.Role
Dataset roles supported by BigQuery. See Also: Dataset Roles
Acl.Routine
Class for a BigQuery Routine entity. Objects of this class represent a routine from a different datasetAclEntity to grant access to. Queries executed against that routine will have read access to views/tables/routines in this datasetAclEntity. Only UDF is supported for now. The role field is not required when this field is set. If that routine is updated by any user, access to the routine needs to be granted again via an update operation.
Acl.User
Class for a BigQuery User entity. Objects of this class represent a user to grant access to given the email address.
Acl.View
Class for a BigQuery View entity. Objects of this class represent a view from a different datasetAclEntity to grant access to. Queries executed against that view will have read access to tables in this datasetAclEntity. The role field is not required when this field is set. If that view is updated by any user, access to the view needs to be granted again via an update operation.

BigQueryError
Google Cloud BigQuery Error. Objects of this class represent errors encountered by the BigQuery service while executing a request. A BigQuery Job that terminated with an error has a non-null JobStatus#getError(). A job can also encounter errors during its execution that do not cause the whole job to fail (see JobStatus#getExecutionErrors()). Similarly, queries and insert all requests can cause BigQuery errors that do not mean the whole operation failed (see JobStatus#getExecutionErrors() and InsertAllResponse#getInsertErrors()). When a BigQueryException is thrown the BigQuery Error that caused it, if any, can be accessed with BigQueryException#getError().

InsertAllRequest.Builder
InsertAllRequest.RowToInsert
A Google Big Query row to be inserted into a table. Each RowToInsert has an associated
id used by BigQuery to detect duplicate insertion requests on a best-effort basis.
To ensure proper serialization of numeric data, it is recommended to supply values using a string-typed representation. Additionally, data for fields of LegacySQLTypeName#BYTES must be provided as a base64 encoded string.
Example usage of creating a row to insert:
List<Long> repeatedFieldValue = Arrays.asList(1L, 2L);
Map<String, Object> recordContent = new HashMap<String, Object>();
recordContent.put("subfieldName1", "value");
recordContent.put("subfieldName2", repeatedFieldValue);
Map<String, Object> rowContent = new HashMap<String, Object>();
rowContent.put("booleanFieldName", true);
rowContent.put("bytesFieldName", "DQ4KDQ==");
rowContent.put("recordFieldName", recordContent);
rowContent.put("numericFieldName", "1298930929292.129593272");
RowToInsert row = new RowToInsert("rowId", rowContent);
See Also: Data Consistency
InsertAllResponse
