------------------------------
Summary: SCM HA performance degradation upon one peer down.
Key: HDDS-5703
URL: https://issues.apache.org/jira/browse/HDDS-5703
Project: Apache Ozone
Issue Type: Bug
Reporter: Mark Gui
When we use the SCM benchmark tool
(https://issues.apache.org/jira/browse/HDDS-5702) to test SCM throughput for
AllocateContainer, we found a dramatic degradation in the throughput when one
scm peer(follower) is down.
Here is some statistics.
Normal Case:
{code:java}
***************************************
Total allocated containers: 500000
Total failed containers: 0
Execution Time: 02:36:50,151
Throughput: 53.000000 (ops)
***************************************
{code}
One scm follower down:
{code:java}
***************************************
Total allocated containers: 50000
Total failed containers: 0
Execution Time: 02:22:00,245
Throughput: 5.000000 (ops)
***************************************
{code}
The overall throughput drops to 1/10 of the original.
