Release Notes

The SymmetricDS Pro Dashboard has been rebuilt with two purpose-built views that give you instant visibility into replication health — no matter how your topology is structured.

The Network View is built for deployments where the central node actively participates in replication. A new Activity panel breaks down replication health across five pipeline stages — Route, Extract, Transfer, Load Out, and Load In — with backlog counts, timing, node coverage, and historical graphs for each stage. Filter by All, Online, or Offline nodes to pinpoint exactly where work is piling up. A companion Throughput panel provides a real-time pulse on data movement across your entire network.

The Pipeline View is purpose-built for hub-and-spoke deployments where the central node acts as a relay. Each endpoint pair is displayed as an individual pipeline with its own status indicator, giving operators an at-a-glance operational board. Common actions like triggering an initial load or pausing replication are available directly from the pipeline grid — no menu hunting required.

The Configure Canvas has been renamed to the Configure Diagram and now supports both network and pipeline layouts. During initial deployment, the Deploy Wizard asks which mode fits your topology. In pipeline mode, the hub node is minimized in the diagram to reduce visual clutter and keep the focus on the endpoint pairs that matter most to your day-to-day operations.

SymmetricDS Pro now supports Databricks as a replication target, providing a direct path from your operational databases to your data lakehouse. The Databricks endpoint operates as write-only, with SymmetricDS runtime metadata stored in a separate H2 database.

The Job Schedule Manager now supports fine-grained scheduling for Push, Pull, and custom jobs (SQL, BeanShell, Java, and more), with minimum intervals tied to your license tier. Standard Pro Edition supports intervals as low as every 1 minute, while Enterprise Pro Edition removes the lower limit entirely — enabling near-real-time push and pull cycles for the most latency-sensitive deployments.

Starting with SymmetricDS 3.17, support for Microsoft SQL Server and Oracle database platforms has moved to SymmetricDS Pro. Organizations using these enterprise databases will benefit from Pro-exclusive capabilities including enhanced monitoring, the redesigned Dashboard, and priority support. Existing open source deployments using these platforms should plan to upgrade to Pro to continue receiving updates and support for these platforms.

Fine-tune how SymmetricDS captures update data on a per-trigger basis. Previously, capturing only changed columns on updates was an all-or-nothing setting at the node level (trigger.update.capture.changed.data.only.enabled). Version 3.17 introduces a capture_changes_only column on sym_trigger, giving you precise control over which tables use change-only capture and which require full row capture — without blanket node-level overrides.

Multi-master and bidirectional deployments with DDL capture enabled no longer need custom workarounds to prevent schema changes from looping back to the originating node. SymmetricDS 3.17 includes built-in DDL loop detection and prevention, ensuring schema changes replicate to their intended targets and stop — making DDL replication production-ready out of the box.

SymmetricDS 3.17 significantly expands the statistics available for monitoring and diagnostics, giving operations teams and monitoring integrations deeper visibility into replication health:

The node_channel_control table now includes a target_node_id column, making it possible to suspend or ignore synchronization between two specific nodes in an individual direction. For ease of use and increased visibility, SymmetricDS now synchronizes this table between nodes via the config channel. In addition, the behavior of this table is more consistent and no longer affected by the group link’s data event action. When upgrading to 3.17, all rows will be deleted from the node_channel_control table.

Monitor events are now routed only upstream to the registration server, instead of being broadcast across every group link. Previously, monitor cycles on the registration server enqueued a batch on the monitor channel for every registered client — including offline ones — which caused outgoing batches to grow steadily until offline nodes reconnected. Monitor events generated on the registration server now stay local, and events generated downstream travel directly to their registration parent. No configuration is required; the new routing behavior is applied automatically on upgrade.

Any monitor batches already pending for an offline client at the time of upgrade will flush and purge automatically the next time that client reconnects. After upgrade no new batches accumulate, so no manual cleanup is needed.
