Atri Sharma commented on LUCENE-8862:
-------------------------------------

Ah, hmm, so your thought is that the memory tracker itself have a limit? That 
is a good idea.

 

The only caveat I could think of in this scenario would be for 
CollectorManagers i.e. does each new Collector get its own Tracker, or is the 
Tracker global to all Collectors? But I guess that is CollectorManager 
dependent i.e. does it want per thread limit, or a global limit...

> Inspired from LUCENE-8855, I am thinking of adding a new interface which 
> tracks dynamic memory used by Collectors. This shall allow users to get an 
> accountability as to the memory usage of their Collectors and better plan 
> their resource capacity. This shall also allow us to add Collector level 
> limits for memory usage, thus allowing users a finer control over their 
> resources.
