Changelog

0.20a3

  • Bug Fixes
    • Always set ImpalaHttpClient.__preserve_all_cookies (#553)

0.20a2

  • Improvements

    • Support wildcard http_cookie_names (#509)
    • Allow skipping utf8 conversion in Python3 (#548)
    • Subtract RPC time from sleep in _wait_to_finish (#551)
    • Reduced logging:
      • Log "Closing operation" at debug level (#539)
      • Never log passwords in http connections (#545)
        • Before the fix passwords were logged at debug level

  • Bug Fixes

    • Turn regex strings into raw strings (#535)
    • Fix SQLAlchemy support for Impala on Python 3.10 (#538)

0.20a1

  • Improvements

    • Add Knox cookies in default cookies list (#525)
    • Support CHAR type in SQLAlchemy (#516)
    • Support Cursor.rowcount and close finished queries (#528) Note that this is a potentially breaking change. See the PR for details about the side-effects. The old behavior can be restored by setting close_finished_queries=False when creating a Cursor. Also note that Cursor.rowcount only works with Impala server - with Hive it will always return -1.

  • Bug Fixes

    • Fix https connection with Python 3.12 (#531) Note that Python 3.12 support is not complete yet. A known issue is that installing with setuptools fails with Python 3.12.
