Limits¶

Tinybird has limits on certain operations and processes to ensure the highest performance.

Workspace limits¶

Description	Limit
Number of Workspaces	Default 90 (soft limit; ask to increase)
Number of seats	Default 90 (soft limit; ask to increase)
Number of Data Sources	Default 100 (soft limit; ask to increase)
Number of Tokens	100,000 (If you need more you should take a look at JWT tokens)
Number of secrets	100
Queries per second	Default 20 (Soft limit. Contact Tinybird Support to increase it.)

See Rate limits for JWTs for more detail specifically on JWT limits.

Ingestion limits¶

Description	Limit
Data Source max columns	500
Full body upload	8MB
Multipart upload - CSV and NDJSON	500MB
Multipart upload - Parquet	50MB
Max file size - Parquet - Build plan	1GB
Max file size - Parquet - Pro and Enterprise plan	5GB
Max file size (uncompressed) - Build plan	10GB
Max file size (uncompressed) - Pro and 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

The quota is shared at Workspaces level when creating, appending data, or replacing data. For example, you can't 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.

The number of rows in append requests does not impact the ingestion limit; each request counts as a single ingestion.

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.

BigQuery Connector limits¶

The import jobs run in a pool, with capacity for up to 2 concurrent jobs. If more scheduled jobs overlap, they're queued.

Description	Limit and time window
Maximum frequency for the scheduled jobs	5 minutes
Maximum rows per append or replace	50 million rows. Exports that exceed this number of rows are truncated to this amount

You can't pause a Data Source with an ongoing import. You must wait for the import to finish before pausing the Data Source.

DynamoDB Connector limits¶

Description	Limit and time window
Storage	500 GB
Throughput	250 Write Capacity Units (WCU), equivalent to 250 writes of at most 1 KB per second

Snowflake Connector limits¶

The import jobs run in a pool, with capacity for up to 2 concurrent jobs. If more scheduled jobs overlap, they're queued.

Description	Limit and time window
Maximum frequency for the scheduled jobs	5 minutes
Maximum rows per append or replace	50 million rows. Exports that exceed this number of rows are truncated to this amount

You can't pause a Data Source with an ongoing import. You must wait for the import to finish before pausing the Data Source.

Query limits¶

Description	Limit
SQL length	8KB
Result length	100 MB
Query execution time	10 seconds

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.

Query timeouts¶

If query execution time exceeds the default limit of 10 seconds, an error message appears. Long execution times hint at issues that need to be fixed in the query or the Data Source schema.

To avoid query timeouts, optimize your queries to remove inefficiencies and common mistakes. See Optimizations for advice on how to detect and solve issues in your queries that might cause timeouts.

If you still need to increase the timeout limit, contact support. See Get help.

Only paid accounts can raise the timeout limit.

Publishing limits¶

Materialized Views limits¶

No numerical limits, certain operations are inadvisable when using Materialized Views.

Sink limits¶

Sink Pipes have the following limits, depending on your billing plan:

Plan	Sink Pipes per Workspace	Execution time	Frequency	Memory usage per query	Active jobs (running or queued)
Pro	3	30s	Up to every 10 min	10 GB	3
Enterprise	10	300s	Up to every minute	10 GB	6

Copy Pipe limits¶

Copy Pipes have the following limits, depending on your billing plan:

Plan	Copy Pipes per Workspace	Execution time	Frequency	Active jobs (running or queued)
Build	1	20s	Once an hour	1
Pro	3	30s	Up to every 10 minutes	3
Enterprise	10	50% of the scheduling period, 30 minutes max	Up to every minute	6

Delete limits¶

Delete jobs have the following limits, depending on your billing plan:

Plan	Active delete jobs per Workspace
Build	1
Pro	3
Enterprise	6
