Description
Original comment: https://github.com/apache/ozone/pull/1680#pullrequestreview-549375494
Summary
Currently we don't have explicit control over how much events Recon will receive on each batch of events from OM. This can lead to Recon OOM like in HDDS-4570 when the max heap is too small and/or OM is too busy and/or sync interval is too long.
A good start point for looking into this might be at OzoneManagerServiceProviderImpl#syncDataFromOM.
