For queries where you want to use fault tolerance for workers, set `faultTolerance` to `true`, which automatically sets `durableShuffleStorage` to `true`.
Set `selectDestination`:`durableStorage` for select queries that want to write the final results to durable storage instead of the task reports. Saving the results in the durable
storage allows users to fetch large result sets. The location where the workers write the intermediate results is different than the location where final results get stored. Therefore, `durableShuffleStorage`:`false` and
`selectDestination`:`durableStorage` is a valid configuration to use in the query context, that instructs the controller to persist only the final result in the durable storage, and not the
intermediate results.
## Durable storage configurations
The following common service properties control how durable storage behaves:
