>                 URL: https://issues.apache.org/jira/browse/HDDS-2384
>             Project: Hadoop Distributed Data Store
>          Issue Type: Improvement
>            Reporter: Rajesh Balamohan
>            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.
