---------------------------------
Summary: 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
As of now we create 60 threads (
dfs.container.ratis.num.write.chunk.threads) to write chunk date 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...
