Description

The concept of Per Replica State (PRS) as a part of state management in Solr has existed since 8.8.0. While PRS is in use in some places, there is still work to be done to get it to a place where we can move to PRS as the default behavior in Solr.

 

This umbrella ticket will encapsulate the work required to get to this point and enable PRS as the default behavior for Solr 10.
