ERR.DS_API.DB.MEMORY_LIMIT_EXCEEDED

There is not enough memory in the data source to run the query.

This error occurs when the database does not have enough memory to execute a DataLens query.

To fix this error, optimize the source table or reduce the amount of data in the query using chart filters.

To optimize tables, contact your database administrator.

If you are going to perform optimization yourself, try enhancing your database with indexes and sorts.

Tip

If you use a ClickHouse® database as a data source, find the DataLens queries in system.query_log.

If you use a PostgreSQL MDB as a data source, check the performance analysis.
