Description

HDDS-10442 added a freon tool dn-echo to microbenchmark the performance of client to DN communication.

 

It is sent in Ratis read only mode so request doesn't get forwarded to followers.

 

This Jira proposes to add

(1) an option --readonly to support read and write mode to benchmark the complete Ratis transactions.

Without --readonly, DataNode interpret the request as write requests.

 

(2)an option --ratis to support both Ratis and GRPC transport.

Without --ratis, client sends request using GRPC transport.
