---------------------------------
Summary: S3g has accumulated memory pressure due to unlimited
ElasticByteBufferPool in RpcClient
Key: HDDS-13400
URL: https://issues.apache.org/jira/browse/HDDS-13400
Project: Apache Ozone
Issue Type: Bug
Reporter: Sammi Chen
The issue is reported by Hao Guo.
Currently RpcClient has a ElasticByteBufferPool to reuse buffers during EC data
read and write. ElasticByteBufferPool can save the time of buffer allocation.
While this Pool doesn't have a upper limit, so in s3g case, a long lived
RpcClient will accumulate all buffers allocated through this pool, which lead
to high memory pressure of s3g.
