[DataLens On-premises] Data source timed out

ERR.DS_API.DB.SOURCE_ERROR.TIMEOUT

Query execution time exceeded for the data source.

Note

DataLens limits the query execution time on the source to 80 seconds.

To fix this error:

  • Optimize the data in the source.
  • Reduce the number of complex expressions with nested aggregations.
  • Reduce the number of fields in the dataset.
  • Create calculated fields at the dataset level instead of fields at the chart level.
