-----------------------------------------
Assignee: Marton Elek
> Decrease the number of the chunk writer threads
> -----------------------------------------------
>
> Key: HDDS-3053
> URL: https://issues.apache.org/jira/browse/HDDS-3053
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Reporter: Marton Elek
> Assignee: Marton Elek
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> As of now we create 60 threads (
> dfs.container.ratis.num.write.chunk.threads) to write chunk data to the disk.
> As the write is limited by the IO I can't see any benefit to have so many
> threads. High number of thread means a high context switch overhead,
> therefore it seems to be more reasonable to use only a limited number of
> threads.
> For example 10 threads should be enough even with 5 external disk.
> If you know any reason to keep the number 60, please let me know...
