Introducing Explorations

While building our own projects, we realized we needed a tool to explore our data, understand its shape, and figure out the right way to query it to get the answers we needed. After a lot of wasted time in the database console, we decided to design what is now called Explorations, a new feature in Tinybird Forward. Explorations is:

  • A notebook-style interface to iteratively explore your data through tables and charts.
  • An AI chat interface to guide your exploration by converting natural language questions into contextualized SQL.

Ingestion Burst Limit Handling for vCPU Usage

Ingestion requests are now monitored against each Organization's vCPU burst limit. When an Organization exceeds this threshold, ingestion is temporarily paused. No data will be lost — ingestion resumes after a short pause (around 1 minute), followed by a gradual recovery. Some data might be delayed by a few minutes, depending on system load.

This ensures fair resource distribution in shared clusters and improves stability under load. This currently applies to Free Plans only.

Events API Request Size Limit Will Be Enforced for Developer Plans Starting August 1, 2025

To ensure consistent high performance and reliability for all Events API users, we will begin enforcing the maximum request size limit on Developer Plans, starting August 1, 2025. As noted in the Events API documentation, the maximum is 10 MB. This limit has already been enforced on Free Plans, and will also be applied to Developer Plans starting August 1.

For the past few weeks, requests exceeding this limit have triggered a warning in the HTTP response body, and an error has been logged in tinybird.datasources_ops_log.

If your requests exceed 10 MB, please split them into smaller batches to avoid rejection. Starting August 1, 2025, requests over the limit will be rejected with an HTTP 413 - Request Entity Too Large error.
