Longer Query API timeouts for paid plans

The default execution timeout for Query API and Pipe endpoint requests is now tiered by plan: 10 seconds on the free plan, 20 seconds on paid plans with shared infrastructure, and 30 seconds on dedicated infrastructure. Workspaces with a custom timeout override keep their existing setting.

New replica column in pipe_stats_rt

The pipe_stats_rt service Data Source now includes a replica column showing which ClickHouse® replica executed each request. Use it to spot load imbalance or latency differences across replicas.

Improvements and bug fixes

  • [All]: Import jobs now use a routing algorithm that picks the least-loaded ClickHouse® replica instead of always using a single fixed server, on clusters with multiple writer replicas.
  • [API]: Fixed browser-based uploads to the v1 Data Source append and replace Endpoints, which previously failed CORS preflight checks.
  • [API]: You can now retry failed or cancelled S3 and GCS sync jobs. Retries skip files that earlier attempts already imported instead of re-importing everything, and work on jobs with many files.
  • [Classic]: Fixed the dashboard Jobs widget showing no results after filtering while on page 2 or later.
  • [Forward]: Deployments no longer fail when a materialized pipe has a leftover alter deployment method directive with nothing left to change; Tinybird shows a warning instead.
