Porting the comment from old PR here
@indrajohn7 This is because SNAPSHOT threadpool can scale up to only 5 threads where as GENERIC threadpool can scale upto 512 depending on no. of cores. |

Description
This PR is to discuss the optimisation changes for listener based get_snapshot calls handled through async based model.
The TransportGetSnapshotAction shouldn't block wait on the
repositoriesService.getRepositoryData and move to async processing
Due to this, pending tasks were stuck for hours on master.
Reproduction:
With Fix:
Use of
SNAPSHOTThreadpoolSNAPSHOTthreadpool in stead ofGENERICthreadpool for the get_snapshot calls.Observations:
*get_snapshot response:
SNAPSHOTthreadpools are lesser compared to the generic one.SNAPSHOTthreadpool would not be recommended here as it may block the create snapshot calls as well if its shared across get_snapshot requests.Related Issues
