PREWHERE clauses are supported in Forward¶

PREWHERE clauses in Pipe SQL are now supported in Forward across all clusters, matching the behavior already available in Classic.

Auto-cleanup for quarantine tables¶

Existing and newly created quarantine tables now have a 1-month TTL. Rows that land in quarantine will be cleaned up automatically after 30 days. This will allow customers to automatically clean up space that is not being used.

TypeScript SDK 0.0.72 and 0.0.73¶

• Multi-argument AggregateFunction types are supported. argMax(String, DateTime), corr(Float64, Float64), sumMap(Array(String), Array(UInt64)), and parameterized variants like quantiles(0.5, 0.9) all round-trip correctly through the type mapper.
• Wider type coverage: Int128, Int256, UInt128, UInt256 are now in the template transform allowlist.
• Pipe generation preserves non-param template helpers like {{ column(...) }} and {{ split_to_array(...) }} instead of trying to inject param metadata into them.

Deprecation: BI Connector reaches end of life on June 30¶

The BI Connector will be removed on June 30, 2026. If you connect BI tools (Grafana, Power BI, Metabase, etc.) to Tinybird, migrate to the ClickHouse® Interface, which exposes the native ClickHouse protocol and works with any BI tool that speaks it. We're reaching out to affected Workspaces directly.

Bug fixes and improvements¶

• [All]: URL import jobs now retry on transient infrastructure failures, with a deduplication token so retried inserts don't produce duplicate rows. User errors like schema mismatches still fail fast.
• [All]: JSON datetime conversion during ingestion is ~3.5x faster. Noticeable on events with many timestamp fields.
• [All]: Hidden Pipe params with a _ prefix (including template loop variables like _last, _col) no longer leak into the UI Parameters panel.
• [All]: Transient Kafka consumer errors no longer surface as user-visible alerts within a short tolerance window.
• [All]: Weekly cost recap email subject now says "weekly" instead of "daily".
• [Forward]: CLI 4.5.7 fixes tb build logs to show the correct resource paths.
• [Forward]: Workspace region menu cleanup, regions are sorted alphabetically grouped by provider, the current Workspace is highlighted correctly, and other regions show even when they have no Workspaces.
• [Forward]: Fix ALTER operations timing out on some TTL modifications due to long mutations.

From the blog¶

No more QPS limits on Developer Plans: QPS limits and overages are gone from Developer Plans. Billing now tracks vCPU-seconds, every plan includes burst capacity (2x to 3x baseline), and ingestion is never throttled.

Hunting orphan objects: 45% off our ClickHouse storage bill (and a near data-loss incident): Engineering deep dive on tracking down petabytes of orphaned objects in object storage, cutting cloud storage costs ~45%, and the near data-loss incident that hardened the recovery procedures along the way.
