SymmetricDS 3.17: Better Visibility, More Connections, and Bidirectional Replication That Just Works

If you run SymmetricDS in production, you know the drill: dozens of nodes, constant data movement, and a dashboard that requires too many clicks to answer the question is everything working?. Version 3.17 is built around fixing that.

This release brings a completely redesigned dashboard experience, four new platform integrations including Databricks and Google Sheets, and a set of hardening improvements that make bidirectional and multi-master deployments significantly easier to operate. Here is what is new.

A Dashboard Built for How You Actually Deploy

The biggest change in 3.17 is the new Pipelines view. If you run hub-and-spoke, you get a dedicated layout where every source and destination pair has its own row: current status, last sync time, pending data counts, and data load progress, all in one place. Color-coded status badges let you spot problems without drilling into detail screens.

Inline action buttons sit directly on each pipeline row, so pausing, resuming, or triggering an initial load is a single click. Named Pipelines let you assign labels like “Store 101 to HQ” that carry through to the Dashboard, Load Data Wizard, and Configure Diagram, which makes large deployments with dozens of pipelines far easier to navigate.

For multi-master topologies where the central node actively participates in replication, the redesigned Network view breaks down health across five stages: Route, Extract, Transfer, Load Out, and Load In. You can see backlog counts, timing, and node coverage at a glance, plus a new Throughput panel that gives you a real-time pulse on data movement across the entire network.

Four New Platform Integrations

3.17 adds native support for four new platforms:

• Databricks and SparkSQL (Pro): Push operational data straight into your lakehouse with native Databricks and SparkSQL support. No custom ETL pipelines or middleware required.
• Google Sheets: Sync data directly to and from Google Sheets for lightweight reporting and collaboration workflows.
• SFTP File Sync: Move files securely alongside your existing file sync mechanisms.
• MinIO File Sync: Bring S3-compatible object storage into your file synchronization workflows.

Bidirectional Replication: DDL Loop Prevention

Schema changes in bidirectional deployments have historically been one of the trickier things to manage in SymmetricDS. In 3.17, built-in DDL loop prevention means schema changes no longer bounce back to the source node. You can use multi-node DDL replication in production without custom workarounds.

Setting up bidirectional replication is also now simpler from the UI. The Configure Diagram includes a new mirror option with active-passive and active-active choices, so you can configure your topology directly from the visual editor.

Deeper Monitoring and Per-Table Change Capture

New tracking columns on sym_node_host_channel_stats, sym_outgoing_batch, and sym_node_host_stats give you better visibility into inbound throughput, end-to-end replication lag, and routing backlogs. If you are trying to pinpoint where slowdowns are happening in a large deployment, these additions make that investigation significantly faster.

A new capture_changes_only column on sym_trigger gives you per-table control over change-only versus full-row capture. This replaces blanket node-level settings and lets you tune capture behavior for individual tables based on your actual use case.

A Note on Oracle and Microsoft SQL Server

Starting with 3.17, Oracle and Microsoft SQL Server support has moved to the Professional edition. If you are planning a new deployment targeting either platform, a SymmetricDS Pro license is required. Existing community edition users should review the upgrade documentation to understand how this affects their environment.

Other Improvements Worth Noting

• Security: CVE-2025-59419 has been addressed, input sanitization has been strengthened, and SSL certificates can now be imported directly from the symconsole command line and pushed to remote nodes.
• Infrastructure: Spring Boot, Spring Security, Gradle (9.30), and H2 (2.4.240) have all been updated. Publishing has moved to Maven Central.

Ready to Upgrade?

SymmetricDS 3.17 is available now. Whether you are managing a handful of nodes or hundreds of endpoints, this release gives you better visibility and more control over your replication network.
