To following resource limitations apply in Data Warehouse.
By default, individual customer queries are not allowed to allocate more than 10 GB of RAM. This limitation may vary depending on your license. For more information, contact GoodData Account Management.
Queries running for longer than 2 hours to execute are terminated.
Sessions open for longer than 2 hours and 10 minutes are terminated.
Parallel Query Limitations
You can have up to 4 queries in parallel per customer token.
If more than 4 queries are executed in parallel, additional queries are queued for running at a later time when resources become available. Resources are checked once per minute.
Each query is allocated memory from your shared memory pool, so you may run into the memory limitations even if you are within your query count limitation.
If queries are queued for more than two hours, they are terminated.Whenever possible, serialize your queries and stagger jobs to prevent overlap.
