What's New in DBConvert Streams
SQL Everywhere. Stream Anything.
Version 2.4.2
Released June 12, 2026
CDC and workspace reliability
No more orphaned replication slots
Deleting a CDC stream config now also drops its PostgreSQL replication slot on the source. Previously the slot stayed behind and silently retained WAL — on a busy source that means unbounded disk growth long after the pipeline is gone.
The docs now also cover how slot WAL retention works and how to cap it with max_slot_wal_keep_size — see CDC reliability and resume.
Connection secrets stay in sync across services
Connections you add or update are now picked up immediately by every running service that shares the workspace — including the MCP server your AI assistant talks to. No restarts after adding a connection: create it in the app, query it from Claude or any MCP client right away.
Version 2.4.0
Released June 10, 2026
AI Assistants via MCP
DBConvert Streams 2.4 ships a built-in MCP server: connect Claude, Cursor, VS Code Copilot, Windsurf, Gemini CLI, or Codex, and your AI assistant reads live schemas, data, and stream state from the same workspace you use — no more pasting DDL and error logs into chat.
What you can do now
- Ask your assistant to describe tables, run read-only SQL, and join data across PostgreSQL, MySQL, and files in one federated query — 26 read-only tools in total.
- Diagnose streams in plain language: status, recent errors, logs, and throughput stats.
- Connect in one click from the new ✨ AI Assistants panel — 7 clients registered automatically, no account required on desktop.
- On Docker deployments, remote AI clients connect over HTTP(S) with your API key.
- Read-only by design: only
SELECTpasses the server-side filter — the AI can look and advise, never write.
The AI Assistants panel detects installed clients and registers the MCP server with one click.
Version 2.3.0
Released May 15, 2026
Paged SQL Console results
Large SELECT / WITH queries now return paged results, so an uncapped query can no longer overwhelm the grid or the backend.
- Page sizes: 50, 100, 250, 500, 1000 rows.
- Default 1,000-row cap for uncapped queries.
- More stable federated MySQL queries.
Version 2.2.0
Released May 11, 2026
Visual Query Plans in SQL Console
DBConvert Streams 2.2 adds visual Query Plans to the SQL Console, making it easier to understand how PostgreSQL, MySQL, and federated queries are executed.
What you can do now
- View query plans directly in the SQL Console.
- Compare estimated vs actual rows, timing, loops, joins, filters, sorting, and indexes where available.
- Switch between a clean visual Plan view and the original raw database output.
- Find performance signals faster with search and Signals only filtering.
- Use a new aggregate validation template for faster cross-database checks.
The Plan view highlights operators, indexes, row estimates, costs, and warning signals.
Select a plan node to inspect filters, joins, timing, loops, and other useful details.
Version 2.1.0
Released April 28, 2026
Safer Run Continuity for CDC and Load
Version 2.1 improves two separate ways to continue interrupted work:
- CDC streams with an initial snapshot now switch into live replication automatically after the snapshot completes, instead of requiring a manual handoff.
- Large supported Load runs can use Resume after Stop so the next start continues from the last saved point instead of restarting the whole load.
CDC Initial Snapshot Improvements
What changes for CDC streams
- Readiness checks: the stream verifies key conditions before the initial snapshot begins
- Automatic handoff to live replication: after the initial snapshot finishes, the stream continues into CDC without a manual operator step
- Easier restart before CDC begins: if the initial snapshot stops, starting the stream again is simpler and more reliable before live replication begins
The Replication Status stepper shows snapshot completion, handoff, and CDC apply while the stream is writing into PostgreSQL.
Resume After Stop for Large Loads
Large supported loads into MySQL or PostgreSQL targets can continue from the last saved point after a stop or interruption, so you do not have to restart the whole load from zero.
Resume from the saved point
When the run supports resume, the next start continues from the last saved point instead of repeating work that already finished.
When a load supports resume, the monitor keeps the saved state visible and lets the operator continue with Resume Load.
Reset when you need a full rerun
If you want a full rerun, Reset clears the saved state first so the next run starts cleanly from the source.
Editor and Connection Improvements
Improved SQL editor
Query results now open below the SQL code instead of in a side pane, and the results grid adds page-size controls and pagination for longer result sets.
The updated SQL editor keeps the query and its results in one vertical flow, with pagination controls at the bottom of the results grid.
Better Supabase connection guidance
Supabase setup is now easier to get right, with clearer connection guidance for direct access, session pooler use, and IPv6-related connection issues.
