----------------------------------

[~ilan] - those performance numbers are against a non PRS version, right? Can 
you run a similar test with PRS and share the results?

> Remove the Overseer {{ClusterStateUpdater}} thread and associated Zookeeper 
> queue at {{<_chroot_>/overseer/queue}}.
> Change cluster state updates so that each (Collection API) command execution 
> does the update directly in Zookeeper using optimistic locking (Compare and 
> Swap on the {{state.json}} Zookeeper files).
> Following this change cluster state updates would still be happening only 
> from the Overseer node (that's where Collection API commands are executing), 
> but the code will be ready for distribution once such commands can be 
> executed by any node (other work done in the context of parent task 
> SOLR-14927).
> See the [Cluster State 
> Updater|https://docs.google.com/document/d/1u4QHsIHuIxlglIW6hekYlXGNOP0HjLGVX5N6inkj6Ok/edit#heading=h.ymtfm3p518c]
