Summary: [hsync] Reduce heap memory allocation in client requests
Key: HDDS-10003
URL: https://issues.apache.org/jira/browse/HDDS-10003
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Wei-Chiu Chuang

In BlockOutputStream, client serializes block token into a string for every request. This is wasteful for applications that send thousands of requests per second.
Proposal: since block token isn't supposed to change (at least within a day), cache the serialized block token and use the string every time.
