Summary: Reduce memory footprint of OMUpdateEventBatch for Recon
Key: HDDS-4570
URL: https://issues.apache.org/jira/browse/HDDS-4570
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Reporter: Siyao Meng
Assignee: Siyao Meng
We are experiencing OOM when Recon heap size is too small (1GB) and it looks
like {{OMUpdateEventBatch#events}} is taking most of them.
Goal:
1. Reduce new object creation when Recon is consuming batches OM events
({{consumeOMEvents}})
2. Improve {{OMUpdateEventBatch#filter}} to reduce memory usage. e.g. avoid
generating a new list?
