Fixed several issues with how empty fields and NULL values were handled during CSV imports through ClickHouse®.

Previously, empty CSV fields in nullable columns could be incorrectly sent to quarantine instead of being stored as NULL. Empty fields in non-nullable columns (like integers) were also quarantined instead of receiving their type's default value (e.g., 0 for Int64).

This also fixes Array columns in CSV imports, which were failing with a TYPE_MISMATCH error because of a conflict between the Nullable(String) intermediate representation and the Array target type.

If you've been working around CSV import quarantine issues, these fixes should resolve them without changes on your side.

The TypeScript SDK now includes a tinybird generate CLI command. It builds Tinybird resources (Data Sources, Pipes, Connections) from your TypeScript include paths and outputs a stable artifact contract that external tools and CI pipelines can consume.

Ingest calls now support automatic retries. Set maxRetries in your ingest options and the SDK handles HTTP 429 (rate limited) and 503 (service unavailable) responses automatically. 429 retries respect Retry-After and X-RateLimit-Reset headers. 503 retries use exponential backoff.

The Endpoint Charts feature has been removed from the Classic UI. This was a rarely used feature for embedding chart visualizations of Endpoint results. If you were using Endpoint Charts, you can build equivalent visualizations using the Endpoint API responses directly.

• Requesting a missing Pipe node now correctly returns a 404 status code instead of 403.
• S3 import file size limits now correctly respect Workspace-level overrides, instead of always applying the default limits.
• JSON type columns are now parsed correctly during populate operations.

How Tinybird's storage architecture works: S3, local caching, and zero-copy replication: How we run ClickHouse® on top of object storage with local SSD caching, zero-copy replication, and a packed part format that cuts S3 costs by 30-40%.

Stay tuned. We have a lot to share. tbrd.co/launch-week
