Improving read/write performance during migrations

There will be increased write load during migrations, which will result in increased read/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” duplicate resolution and get enhanced read/write performance.

To disable duplicate resolution , run the following command on all the nodes.

CODE: SELECT ALL
clinfo -v "set-config:context=service;write-duplicate-resolution-disable=true" -h [host ip]
