  • v3.3.0(October 10,2023)

    • Updated to Apache arrow-nanoarrow project for result arrow data conversion.
    • Introduced the NANOARROW_USAGE environment variable to allows switching between the nanoarrow converter and the arrow converter. Valid values include:
      • FOLLOW_SESSION_PARAMETER, which uses the converter configured in the server.
      • DISABLE_NANOARROW, which uses arrow converter, overriding the server setting.
      • ENABLE_NANOARROW, which uses the nanoarrow converter, overriding the server setting.
    • Introduced the snowflake.connector.cursor.NanoarrowUsage enum, whose members include:
      • NanoarrowUsage.FOLLOW_SESSION_PARAMETER, which uses the converter configured in the server.
      • NanoarrowUsage.DISABLE_NANOARROW, which uses arrow converter, overriding the server setting.
      • NanoarrowUsage.ENABLE_NANOARROW, which uses the nanoarrow converter, overriding the server setting.
    • Introduced the snowflake.connector.cursor.NANOARROW_USAGE module variable to allow switching between the nanoarrow converter and the arrow converter. It works in conjunction with the snowflake.connector.cursor.NanoarrowUsage enum.
    • The newly-introduced environment variable, enum, and module variable are temporary. They will be removed in a future release when switch from arrow to nanoarrow for data conversion is complete.
