v2.3.14 Release

• Adds support for withApplicationDefaultCredentials=<bool> param that will use the application default credential to authenticate a BQ connection. This param takes the lowest precedence over other auth methods (i.e. withServiceAccount andoAuthAccessToken).

• Adds a new URL param targetServiceAccount=<String> to allow for service account "impersonation" e.g. targetServiceAccount=<service-account>@<project>.iam.gserviceaccount.com Choosing an auth method is still required so, for example, withApplicationDefaultCredentials=true&targetServiceAccount=<service-account-email> would use the application default as source and attempt to impersonate the target account.

• Adds improved support for BigQuery BI Engine acceleration statistics and job tracking.

v2.3.13 Release

Addresses an issue from v2.3.12 which changed how invalid oauth tokens were handled.

Update Google Auth libraries

• Updates to latest google auth libraries for handling OAuth and service accounts.
• Formats code with google-java-format

v2.3.11 Release

• Make getTotalBytesProcessed() and getCacheHit() nullable. A null value indicates that the total_bytes_processed or cache_hit fields were omitted from a query response, generally because they are not applicable to some query. This could be due to the query being non-standard SQL, e.g. storing procedures, or due to the configuration of the database, e.g. row-level ACL's prevent reporting of total_bytes_processed to avoid leaking table size information. They are liable to be null for any query.
• Add a timeoutMs JDBC parameter to override the default timeout, which is effectively indefinite.

v2.3.10 Release

Enrich the error message for BQSQLException message for all Exceptions rather than simply the GoogleJsonResponseException

v2.3.9 Release

Add a boolean parameter queryCache to control whether or not to use BigQuery's query cache. Enabled (true) by default. Setting it to anything besides true (case-insensitive) will disable the cache.

v2.3.8 Release

Fix NPE error in async query path.

v2.3.7 Release

Fix NPE being thrown due to fields being absent in query responses. Generally robustify our handling of these responses.

v2.3.6 release

Add support for Geography field types

v2.3.5 Release

Add support for getting totalBytesProcessed and cacheHit from results sets.
