Andrzej Bialecki commented on SOLR-14486:
-----------------------------------------
I changed the implementation so that it maintains individual collection states
and their versions, and maintains corresponding /state.json files. This
actually makes the caching and locking behavior in {{SimClusterStateProvider}}
easier to understand - and it also keeps the state in pseudo-ZK exactly as if
it was created by real Solr.
> Autoscaling simulation framework should stop using /clusterstate.json

> In theory the simulation framework doesn't actually use this file, but
> {{SimClusterStateProvider}} relies on its versioning to keep its internal
> data structures in sync. This should be changed to use individual
> DocCollection / state.json znodeVersion instead.
