Debezium 3.6.0.CR1, the first candidate release for the 3.6 milestone, introduces several enhancements: off-heap memory management for table history and schemas using RocksDB, a 75% reduction in memory allocation and 31–42% CPU overhead reduction in the MySQL connector's poll path, Spanner Omni compatibility, a monitoring REST API and multi-panel dashboard in Debezium Platform, and JDBC sink support in Platform. Oracle connector improvements include better diagnostics for missing archive logs, a unified JDBC driver version, exponential back-off for XStream attach retries, deferred transaction creation until first DML, and filtering of PRIVATE redo thread logs in RAC environments. Bug fixes address a KafkaSchemaHistory recovery race condition, PostgreSQL varbit column handling, Vitess timestamp processing, NanoTimestamp overflow for extreme dates, and CockroachDB temporal type alignment. A total of 44 issues were resolved.
