Ingestion limits¶
| Description | Limit |
|---|---|
| Data Source max columns | 2,048 |
| Full body upload | 8MB |
| Multipart upload - CSV and NDJSON | 500MB |
| Multipart upload - Parquet | 50MB |
| Max file size - Parquet | 1GB |
| Max file size (uncompressed) - Build plan | 10GB |
| Max file size (uncompressed) - Pro or Enterprise plan | 32GB |
| Kafka topics | Default 5 (soft limit; ask to increase) |
| Max parts created at once - NDJSON/Parquet jobs and Events API | 12 |
Ingestion limits (API)¶
Tinybird throttles requests based on the capacity. So if your queries are using 100% resources you might not be able to run more queries until the running ones finish.
| Description | Limit and time window |
|---|---|
| Request size - Events API | 10MB |
| Response size | 100MB |
| Create Data Source from schema | 25 times per minute |
| Create Data Source from file or URL* | 5 times per minute |
| Append data to Data Source* | 5 times per minute |
| Append data to Data Source using v0/events | 1,000 times per second |
| Replace data in a Data Source* | 5 times per minute |
*Note that the quota for "Create Data Source from file or URL", "Append to Data Source", and "Replace data in Data Source" is shared. That is, you cannot do 5 requests of each type per minute, for a total of 15 requests. You can do at most a grand total of 5 requests of those types combined.
If you exceed your rate limit, your request will be throttled and you will receive HTTP 429 Too Many Requests response codes from the API. Each response contains a set of HTTP headers with your current rate limit status.
| Header Name | Description |
|---|---|
X-RateLimit-Limit | The maximum number of requests you're permitted to make in the current limit window. |
X-RateLimit-Remaining | The number of requests remaining in the current rate limit window. |
X-RateLimit-Reset | The time in seconds after the current rate limit window resets. |
Retry-After | The time to wait before making a another request. Only present on 429 responses. |
Snowflake & BigQuery Connector limits¶
The import jobs are run in a pool, with capacity for up to 2 concurrent jobs. If more scheduled jobs overlap, they are queued.
| Description | Limit and time window |
|---|---|
| Maximum frequency for the scheduled jobs | 5 minutes |
| Maximum rows per append or replace (exports that exceed this number of rows will be truncated to this amount) | 50 million rows |
