v4.0.0-rc3

Migration

• Migration from 4.0.0-rc2 is supported. No changes required.
• Migration from 4.0.0-rc1 is not supported.
• Migration from versions 3.x and 2.x is not supported

• FLOW-7323 - Pass private key password to ingestion client by @sfc-gh-lkucharski in #1223
• NO-SNOW Release 4.0.0-rc3 by @sfc-gh-lkucharski in #1224

v4.0.0-rc2

Breaking Changes

• The class name of the main connector class has been changed from snowflake.kafka.connector.SnowflakeSinkConnector to com.snowflake.kafka.connector.SnowflakeStreamingSinkConnector
• snowflake.role.name configuration parameter is no longer optional
• SNOWPIPE channel naming convention has changed; the connector name is now prefixed to the name to prevent name collisions
• RECORD_CONTENT umbrella column used by the connector when schematization was disabled is not supported; SMT transformation can be used to achieve the same result
• Schematization is now enabled and can't be turned off. The first-level fields from the message content are now mapped to the column names

Warning

The configuration settings from version 4.0.0-rc1 will not work with this release. We do not recommend migrating the connectors running earlier versions to this release. Instead, create the new connectors and start over the ingestion pipelines.
