Problem Description
Increase in write latency are only observed during migrations.Explanation
There will be increased write load during migrations, which may result in increased write latency. This increased latency is the result of the server running "on-demand" duplicate resolution for maintaining consistency.If latency is critical and consistency requirements can be relaxed, it is possible to disable "on-demand" write duplicate resolution and get enhanced write performance.Solution
To disable write duplicate resolution, run the following command on all the nodes:
asinfo -v "set-config:context=namespace;id=test;disable-write-dup-res=true" -h [host ip]
