Subject Re: About Rebalance Mode (SYNC & NONE)
Date Sun, 03 May 2020 19:41:01 GMT
Hi.

You are correct, NONE is a legacy mode and should be removed [1]

Note the baseline can be used with in-memory caches as well. To make it
working you have to disable baseline auto-adjust or set non-zero
auto-adjust timeout.
This will prevent unnecessary rebalancing.
