v1.3.10 (2026-06-24)

New Features

• Added clusterName configuration option. When set, the connector includes an ON CLUSTER '<name>'
  clause in the distributed DDL it runs (e.g. the ALTER TABLE ... ADD COLUMN statements issued by
  auto.evolve), so schema evolution propagates across all replicas in a clustered deployment. Empty by
  default. (#716, #738)

Bug Fixes

• Inserts now time out instead of blocking forever when ClickHouse becomes unresponsive (network partition,
  server hang, long GC pause). Previously a stuck insert could hold the task past
  consumer.override.max.poll.interval.ms, causing Kafka to rebalance the partitions mid-insert. The new
  clickhouseClientInsertTimeoutMs setting (default 240000) bounds the wait; on timeout a retriable
  exception is thrown so the Connect framework retries the batch. Set this below
  consumer.override.max.poll.interval.ms. (#756)

Improvements

• Reduced log noise: messages about unhandled complex sub-types encountered while building table mappings
  are now logged at DEBUG instead of WARN, since they are expected and not errors.
  (#767)

Dependencies

• Bumped org.projectlombok:lombok from 1.18.38 to 1.18.46.

  (gradle/libs.versions.toml) and the jvm-test-suite plugin.
