Shalin Shekhar Mangar updated SOLR-7372:
----------------------------------------
Attachment: SOLR-7372.patch
# Changed AtomicLong to a simple long because it is always read/written inside
synchronized(map)
# Changed ramBytesUsed() to also use the same synchronization
# Renamed 'evictionsDueToRamBytes' to 'evictionsRamUsage' -- this counter will
track number of evictions that happen because we exceeded the maxRamBytes -
please note [~erickerickson].
I'll commit this shortly.

> Now that SOLR-7371 has made DocSet impls Accountable, we should add an option
> to LRUCache to limit itself by RAM.
> I propose to add a 'maxRamBytes' configuration parameter which it can use to
> evict items once the total RAM usage of the cache reaches this limit.
