> Between SCM *IncrementalContainerReportHandler* and *ReconIncrementalContainerReportHandler* , Recon always connecting to SCM and verifying for each container before adding new container to its own containerStateManager cache. This could be a bottle neck if SCM may respond slow and frequent ICR requests may pile up in queue. So as of now, we'll improve multiple things as part of this JIRA:
> * Recon to verify containers in batches from SCM on receive of ICR request from DNs.
> * Reduce the scmClient configs for Recon before connecting to SCM:
> ** hdds.scmclient.rpc.timeout - 1 min (Default value is 15 mins)
> ** hdds.scmclient.failover.max.retry - 3 (Default value is dynamic and computed, but based on default values, computed value is 15)
> Above 2 SCM client configs will be updated to respective new values as mentioned for recon to connect to SCM. These 2 SCM client configs will be exposed and mapped with new recon configs to be able to adjust independently in recon.
> *New configs in Recon:*
> *
> ** ozone.recon.scmclient.rpc.timeout
> ** ozone.recon.scmclient.failover.max.retry
> * Merge the Incremental container report (ICR) to existing list of ICR reports.
