runzhiwang updated HDDS-3168:
-----------------------------
Description: Read a 100MB object which 25 chunks, the jaeger trace
information as the image shows. Now ozone read each chunk in sequential order,
it can be improve by reading chunks in parallel. And the rpc call is also too
many, it can be improve by one rpc call and return the result by batch.

trace information as the image shows. Now ozone read each chunk in sequential
order, but I think these chunks can be read in parallel. And the cost of
getContainerWithPipeline is 1-3 ms, which is also too long. !screenshot-3.png!
