----------------------------------
Assignee: Anu Engineer
> Large chunks during write can have memory pressure on DN with multiple clients
> ------------------------------------------------------------------------------
>
> Key: HDDS-2384
> URL: https://issues.apache.org/jira/browse/HDDS-2384
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Reporter: Rajesh Balamohan
> Assignee: Anu Engineer
> Priority: Major
> Labels: performance
>
> During large file writes, it ends up writing {{16 MB}} chunks.
> https://github.com/apache/hadoop-ozone/blob/master/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/keyvalue/KeyValueHandler.java#L691
> In large clusters, 100s of clients may connect to DN. In such cases,
> depending on the incoming write workload mem load on DN can increase
> significantly.
