The ExtractNewDocumentState and EventRouter SMTs now propagate any heartbeat or schema change messages unchanged instead of dropping them as before. This is to ensure consistency with the ExtractNewRecordState SMT (DBZ-1513).
The new Postgres connector option interval.handling.mode allows to control whether INTERVAL columns should be exported as microseconds (previous behavior, remains the default) or as ISO 8601 formatted string (DBZ-1498). The following upgrade order must be maintained when existing connectors capture INTERVAL columns:
- Upgrade the Debezium Kafka Connect Postgres connector
- Upgrade the logical decoding plug-in installed in the database
- (Optionally) switch
interval.handling.modeto string
In particular it should be avoided to upgrade the logical decoding plug-in before the connector, as this will cause no value to be exported for INTERVAL columns.

Transaction id (txId field of Envelope) for PostgreSQL was originally encoded as an 32-bit integer type.
The real range is a 64-bit long type so this was changed in DBZ-673.
The datatypes without timezone were not correctly offsetted for databases running in non-UTC timezones. This was fixed in DBZ-587 and DBZ-741. See MySQL and PostgreSQL connector documentation for further details.

November 9, 2016 - Detailed release notes
This release includes the following feature:
- MySQL connector now supports failover to MySQL masters that are slaves of multiple other MySQL servers/clusters. DBZ-143
None
This release includes the following significant fix, and all users are strongly encouraged to upgrade:
- Restarting MySQL connector may lose or miss events from the previous transaction that was incompletely processed prior to the easlier shutdown. This fix corrects this potential problem and slightly alters the offsets recorded by the connector. Production connectors should be stopped carefully to ensure transactions are processed atomically, if necessary by temporarily stopping updates on the MySQL server and letting the connector complete all transactions before stopping. DBZ-144
Additionally, this release includes the following fixes since the 0.3.4 release:
- Shutting down MySQL connector task database and quickly terminating the Kafka Connect process may cause connector to be restarted in a strange state when Kafka Connect is restarted, but this no longer results in a null pointer exception in the Kafka database history. DBZ-146
- MySQL connector now has option to treat
DECIMALandNUMERICcolumns as double values rather thanjava.math.BigDecimalvalues that are encoded in the messages by Kafka Connect in binary form. DBZ-147 - MySQL connector tests now take into account daylight savings time in the expected results. DBZ-148
- MySQL connector now properly treats
BINARYcolumns as binary values rather than string values. DBZ-149 - MySQL connector now handles updates to a row's primary/unique key by issuing
DELETEand tombstone events for the row with the old key, and then anINSERTevent for the row with the new key. Previously, theINSERTwas emitted before theDELETE. DBZ-150 - MySQL connector now handles
ENUMandSETliterals with parentheses. DBZ-153

None
This release includes all of the fixes from the 0.2.4 release, and also includes the following fixes:
- MySQL connector now properly decodes string values from the binlog based upon the column's character set encoding as read by the DDL statement. Upon upgrade and restart, the connector will re-read the recorded database history and now associate the columns with their the character sets, and any newly processed events will use properly encoded strings values. As expected, previously generated events are never altered. Force a snapshot to regenerate events for the servers. DBZ-102
- Corrected how the MySQL connector parses some DDL statements. DBZ-106
- Corrected the MySQL connector to handle MySQL server GTID sets with newline characters. DBZ-107, DBZ-111
- Corrected the MySQL connector's startup logic properly compare the MySQL SSL-related system properties to prevent overwriting them. The connector no longer fails when the system properties are the same, which can happen upon restart or starting a second MySQL connector with the same keystore. DBZ-112
- Removed unused code and test case. DBZ-108
- Ensure that the MySQL error code and SQLSTATE are included in exceptions reported by the connector. DBZ-109
August 16, 2016 - Detailed release notes
- New MongoDB connector supports capturing changes from a MongoDB replica set or a MongoDB sharded cluster. See the documentation for details. DBZ-2
- Upgraded to Kafka 0.10.0.1, which means that the Debezium connectors can only be used with Kafka Connect 0.10.0.1. Check Kafka documentation for compatibility with other versions of Kafka brokers. DBZ-62, DBZ-80
- By default the MySQL connector now represents temporal values with millisecond, microsecond, or nanosecond precision based upon the precision of the source database columns. This changes the schema name of these fields to Debezium-specific constants, and the meaning/interpretation of the literal values now depends on this schema name. To enable previous behavior that always used millisecond precision using only Kafka Connect logical types, set
time.precision.modeconnector property toconnect. DBZ-91 - Removed several methods in the
GtidSetclass inside the MySQL connector. The class was introduced in 0.2. This change will only affect applications explicitly using the class (by reusing the MySQL connector JAR), and will not affect how the MySQL connector works. Changed in 0.2.2. DBZ-79 - The
sourcefield within each MySQL change event now contains the binlog position of that event (rather than the next event). Events persisted by earlier versions of the connector are unaffected. This change may adversely clients that are directly using the position within thesourcefield. Changed in 0.2.2. DBZ-76 - Correted the names of the Avro-compliant Kafka Connect schemas generated by the MySQL connector for the
beforeandafterfields in its data change events. Consumers that require knowledge (by name) of the particular schemas used in 0.2 events may have trouble consuming events produced by the 0.2.1 (or later) connector. Fixed in 0.2.1. DBZ-72
- MySQL snapshots records DDL statements as separate events on the schema change topic. DBZ-97
- MySQL connector tolerates binlog filename missing from ROTATE events in certain situations. DBZ-95
- Stream result set rows when taking snapshot of MySQL databases to prevent out of memory problems with very large databases. Fixed in 0.2.4. DBZ-94
- Add more verbose logging statements to the MySQL connector to show progress and activity. Fixed in 0.2.4. DBZ-92
- Corrected potential error during graceful MySQL connector shutdown. Fixed in 0.2.4. DBZ-103
- The Kafka Connect schema names used in the MySQL connector's change events are now always Avro-compatible schema names DBZ-86
- Corrected parsing errors when MySQL DDL statements are generated by Liquibase. Fixed in 0.2.3. DBZ-83
- Corrected support of MySQL
TINYINTandSMALLINTtypes. Fixed in 0.2.3. DBZ-84, DBZ-87 - Corrected support of MySQL temporal types, including
DATE,TIME, andTIMESTAMP. Fixed in 0.2.3. DBZ-85 - Corrected support of MySQL
ENUMandSETtypes. DBZ-100 - Corrected call to MySQL
SHOW MASTER STATUSso that it works on pre-5.7 versions of MySQL. Fixed in 0.2.3. DBZ-82 - Correct how the MySQL connector records offsets with multi-row MySQL events so that, even if the connector experiences a non-graceful shutdown (i.e., crash) after committing the offset of some of the rows from such an event, upon restart the connector will resume with the remaining rows in that multi-row event. Previously, the connector might incorrectly restart at the next event. Fixed in 0.2.2. DBZ-73
- Shutdown of the MySQL connector immediately after a snapshot completes (before another change event is reccorded) will now be properly marked as complete. Fixed in 0.2.2. DBZ-77
- The MySQL connector's plugin archive now contains the MySQL JDBC driver JAR file required by the connector. Fixed in 0.2.1. DBZ-71

beforeandafterfields in its data change events. Consumers that require knowledge (by name) of the particular schemas used in 0.2 events may have trouble consuming events produced by the 0.2.1 (or later) connector. (DBZ-72)
- The MySQL connector's plugin archive now contains the MySQL JDBC driver JAR file required by the connector.(DBZ-71)
June 8, 2016 - Detailed release notes
- MySQL connector supports high availability MySQL cluster topologies. See the documentation for details. (DBZ-37)
- MySQL connector now by default starts by performing a consistent snapshot of the schema and contents of the upstream MySQL databases in its current state. See the documentation for details about how this works and how it impacts other database clients. (DBZ-31)
- MySQL connector can be configured to exclude, truncate, or mask specific columns in events. (DBZ-29)
- MySQL connector events can be serialized using the Confluent Avro converter or the JSON converter. Previously, only the JSON converter could be used. (DBZ-29, DBZ-63, DBZ-64)
- Completely redesigned the structure of event messages produced by MySQL connector and stored in Kafka topics. Events now contain an envelope structure with information about the source event, the kind of operation (create/insert, update, delete, read), the time that Debezium processed the event, and the state of the row before and/or after the event. The messages written to each topic have a distinct Avro-compliant Kafka Connect schema that reflects the structure of the source table, which may vary over time independently from the schemas of all other topics. See the documentation for details. This envelope structure will likely be used by future connectors. (DBZ-50, DBZ-52, DBZ-45, DBZ-60)
- MySQL connector handles deletion of a row by recording a delete event message whose value contains the state of the removed row (and other metadata), followed by a tombstone event message with a null value to signal Kafka's log compaction that all prior messages with the same key can be garbage collected. See the documentation for details. (DBZ-44)
- Changed the format of events that the MySQL connector writes to its schema change topic, through which consumers can access events with the DDL statements applied to the database(s). The format change makes it possible for consumers to correlate these events with the data change events. (DBZ-43, DBZ-55)
- DDL parsing framework identifies table affected by statements via a new listener callback. (DBZ-38)
- The
database.binlogconfiguration property was required in version 0.1 of the MySQL connector, but in 0.2 it is no longer used because of the new snapshot feature. If provided, it will be quietly ignored. (DBZ-31)
- MySQL connector now properly parses
COMMITstatements, theREFERENCESclauses ofCREATE TABLEstatements, and statements withCHARSETshorthand ofCHARACTER SET. (DBZ-48, DBZ-49, DBZ-57) - MySQL connector properly handles binary values that are hexadecimal strings (DBZ-61)
