Bump snowflake-connector-python from 3.13.0 to 3.16.0

[dependabot]

Bumps snowflake-connector-python from 3.13.0 to 3.16.0.

Release notes

Sourced from snowflake-connector-python's releases.

3.16.0

• v3.16.0(July 04,2025)
  • Bumped numpy dependency from <2.1.0 to <=2.2.4.
  • Added Windows support for Python 3.13.
  • Added bulk_upload_chunks parameter to write_pandas function. Setting this parameter to True changes the behaviour of write_pandas function to first write all the data chunks to the local disk and then perform the wildcard upload of the chunks folder to the stage. In default behaviour the chunks are being saved, uploaded and deleted one by one.
  • Added support for new authentication mechanism PAT with external session ID.
  • Added client_fetch_use_mp parameter that enables multiprocessed fetching of result batches.
  • Added basic arrow support for Interval types.
  • Fixed write_pandas special characters usage in the location name.
  • Fixed usage of use_virtual_url when building the location for gcs storage client.
  • Added support for Snowflake OAuth for local applications.

3.15.0

• v3.15.0(Apr 29,2025)
  • Bumped up min boto and botocore version to 1.24.
  • OCSP: terminate certificates chain traversal if a trusted certificate already reached.
  • Added new authentication methods support for programmatic access tokens (PATs), OAuth 2.0 Authorization Code Flow, OAuth 2.0 Client Credentials Flow, and OAuth Token caching.
    • For OAuth 2.0 Authorization Code Flow:
      • Added the oauth_client_id, oauth_client_secret, oauth_authorization_url, oauth_token_request_url, oauth_redirect_uri, oauth_scope, oauth_disable_pkce, oauth_enable_refresh_tokens and oauth_enable_single_use_refresh_tokens parameters.
      • Added the OAUTH_AUTHORIZATION_CODE value for the parameter authenticator.
    • For OAuth 2.0 Client Credentials Flow:
      • Added the oauth_client_id, oauth_client_secret, oauth_token_request_url, and oauth_scope parameters.
      • Added the OAUTH_CLIENT_CREDENTIALS value for the parameter authenticator.
    • For OAuth Token caching: Passing a username to driver configuration is required, and the client_store_temporary_credential property is to be set to true.

3.14.1

• v3.14.1(April 21, 2025)
  • Added support for Python 3.13.
    • NOTE: Windows 64 support is still experimental and should not yet be used for production environments.
  • Dropped support for Python 3.8.
  • Added basic decimal floating-point type support.
  • Added experimental authentication methods.
  • Added support of GCS regional endpoints.
  • Added support of GCS virtual urls. See more: https://cloud.google.com/storage/docs/request-endpoints#xml-api
  • Added client_fetch_threads experimental parameter to better utilize threads for fetching query results.
  • Added check_arrow_conversion_error_on_every_column connection property that can be set to False to restore previous behaviour in which driver will ignore errors until it occurs in the last column. This flag's purpose is to unblock workflows that may be impacted by the bugfix and will be removed in later releases.
  • Lowered log levels from info to debug for some of the messages to make the output easier to follow.
  • Allowed the connector to inherit a UUID4 generated upstream, provided in statement parameters (field: requestId), rather than automatically generate a UUID4 to use for the HTTP Request ID.
  • Improved logging in urllib3, boto3, botocore - assured data masking even after migration to the external owned library in the future.
  • Improved error message for client-side query cancellations due to timeouts.
  • Improved security and robustness for the temporary credentials cache storage.
  • Fixed a bug that caused driver to fail silently on TO_DATE arrow to python conversion when invalid date was followed by the correct one.
  • Fixed expired S3 credentials update and increment retry when expired credentials are found.
  • Deprecated insecure_mode connection property and replaced it with disable_ocsp_checks with the same behavior as the former property.

3.14.0

• v3.14.0(March 03, 2025)
  • Bumped pyOpenSSL dependency upper boundary from <25.0.0 to <26.0.0.
  • Added a <19.0.0 pin to pyarrow as a workaround to a bug affecting Azure Batch.
  • Optimized distribution package lookup to speed up import.
