Service Data Sources¶

Tinybird provides Service Data Sources that you can use to inspect what's going on in your Tinybird account, diagnose issues, monitor usage, and so on.

For example, you can get real time stats about API calls or a log of every operation over your Data Sources. This is similar to using system tables in a database, although Service Data Sources contain information about the usage of the service itself.

Queries made to Service Data Sources are free of charge and don't count towards your usage. However, calls to API Endpoints that use Service Data Sources do count towards API rate limits. Read the billing docs.

Considerations¶

You can't use Service Data Sources in Materialized View queries.
Pass dynamic query parameters to API Endpoints to then query Service Data Sources.
You can only query Organization-level Service Data Sources if you're an administrator. See Consumption overview.

Service Data Sources¶

The following Service Data Sources are available.

Use resource_tags to better track usage¶

You can use tags that you've added to your resources, like Pipes or Data Sources, to analyze usage and cost attribution across your organization.

For example, you can add tags for projects, environments, or versions and compare usage in later queries to Service Data Sources such as tinybird.datasources_ops_stats, which aggregates operations data by day.

The following Service Data Sources support resource_tags:

pipe_stats_rt
pipe_stats
endpoint_errors
organization.pipe_stats_rt
organization.pipe_stats
datasources_ops_log
datasources_ops_stats
organization.datasources_ops_log
organization.datasources_ops_stats

To add tags to resources, see Organizing resources in Workspaces.

Query _state columns¶

Several of the Service Data Sources include columns suffixed with _state. This suffix identifies columns with values that are in an intermediate aggregated state. When reading these columns, merge the intermediate states to get the final value.

To merge intermediate states, wrap the column in the original aggregation function and apply the -Merge combinator.

For example, to finalize the value of the avg_duration_state column, you use the avgMerge function:

finalize the value for the avg_duration_state column

SELECT
  date,
  avgMerge(avg_duration_state) avg_time,
  quantilesTimingMerge(0.9, 0.95, 0.99)(quantile_timing_state) quantiles_timing_in_ms_array
FROM tinybird.pipe_stats
where pipe_id = 'PIPE_ID'
group by date

Learn more about the -Merge combinator in the ClickHouse® documentation.
