Release Notes for Debezium 1.1

Release 1.1.1.Final (April 17th, 2020)

Kafka compatibility

This release has been built against Kafka Connect 2.4.1 and has been tested with version 2.4.1 of the Kafka brokers. See the Kafka documentation for compatibility with other versions of Kafka brokers.

Upgrading

Before upgrading the MySQL, MongoDB, PostgreSQL, SQL Server, Cassandra or DB2 connectors, be sure to check the backward-incompatible changes that have been made since the release you were using.

When you decide to upgrade one of these connectors to 1.1.1.Final from any of the earlier 1.1.x, 1.0.x, 0.10.x, 0.9.x, 0.8.x, 0.7.x, 0.6.x, 0.5.x, 0.4.x, 0.3.x, 0.2.x, or 0.1.x versions, first check the upgrading notes for the version you’re using. Gracefully stop the running connector, remove the old plugin files, install the 1.1.1.Final plugin files, and restart the connector using the same configuration. Upon restart, the 1.1.1.Final connectors will continue where the previous connector left off. As one might expect, all change events previously written to Kafka by the old connector will not be modified.

If you are using our docker images then do not forget to pull them fresh from Docker registry.

Breaking changes

The default value of MySQL config option gtid.new.channel.position was originally set to latest that should never be used in a production. The default value was thus set to earliest and the config option is scheduled for removal (DBZ-1705). The MySQL config option event.deserialization.failure.handling.mode was renamed to event.processing.failure.handling.mode to make the naming consistent with other connectors (DBZ-1826). MongoDB config option field.renames adds renamed field (wtih null value) even when the source field is missing. This was identified as a defect and the non-present fields are no longer added (DBZ-1848).

New Features

  • Distinguish between public (API) and internal parts of Debezium DBZ-234

  • Default gtid.new.channel.position to earliest DBZ-1705

  • Add option to skip unprocesseable event DBZ-1760

  • ExtractNewRecordState - add.source.fields should strip spaces from comma-separated list of fields DBZ-1772

  • Add support for update events for sharded MongoDB collections DBZ-1781

  • Useless/meaningless parameter in function DBZ-1805

  • Replace BlockEventQueue with Debezium ChangeEventQueue DBZ-1820

  • Option to configure column.propagate.source.type on a per-type basis, not per column-name basis DBZ-1830

  • Support MongoDB Oplog operations as config DBZ-1831

  • Add app metrics for mongodb connector to jmx DBZ-845

  • Provide SPI to override schema and value conversion for specific columns DBZ-1134

  • Retry polling on configured exceptions DBZ-1723

Fixes

This release includes the following fixes:

  • CDC Event Schema Doesn’t Change After 2 Fields Switch Names and Places DBZ-1694

  • TINYINT(1) value range restricted on snapshot. DBZ-1773

  • MySQL source connector fails while parsing new AWS RDS internal event DBZ-1775

Breaking changes

Before updating the DecoderBufs logical decoding plug-in in your Postgres database to this new version (or when pulling the debezium/postgres container image for that new version), it is neccessary to upgrade the Debezium Postgres connector to 1.0.1.Final or 1.1.0.Alpha2 or later (DBZ-1052).

The ExtractNewDocumentState SMT to be used with the Debezium MongoDB connector will convert Date and Timestamp fields now into the org.apache.kafka.connect.data.Timestam`p logical type, clarifying its semantics. The schema type itself remains unchanged as `int64. Please note that the resolution of Timestamp is seconds as per the semantics of that type in MongoDB. (DBZ-1717).

  • Create a plug-in for DB2 streaming DBZ-695

  • Add topic routing by field option for New Record State Extraction DBZ-1715

  • Generate date(time) field types in the Kafka Connect data structure DBZ-1717

Breaking changes

When using the outbox event routing SMT and configuring a column from which to obtain the Kafka record timestamp from (table.field.event.timestamp option), then that value could have been exported as milliseconds, microseconds or nanoseconds, based on the source column’s definition.
