Andrzej Bialecki commented on SOLR-9658:
-----------------------------------------
Here's an updated patch - I tried to address all your concerns:
* removed the CacheListener API
* refactored cache impls to allow inserting synthetic entries, and changed the
unit tests to use these methods. It turned out that the management of
{{oldestEntry}} needs to be improved in all caches when we allow the creation
time in more recently added entries to go back...
* currently unit tests test only the first part - "what happens when
markAndSweep() is called on a cache with specific entries". I'll add the other
part if this patch looks ok.
> Caches should have an optional way to clean if idle for 'x' mins

> If a cache is idle for long, it consumes precious memory. It should be
> configurable to clear the cache if it was not accessed for 'x' secs. The
> cache configuration can have an extra config {{maxIdleTime}} . if we wish it
> to the cleaned after 10 mins of inactivity set it to {{maxIdleTime=600}}.
> [~dragonsinth] would it be a solution for the memory leak you mentioned?
