> Reduce heap occupation by

> Key: IGNITE-10913
> URL: https://issues.apache.org/jira/browse/IGNITE-10913
> Project: Ignite
> Issue Type: Improvement
> Reporter: Alexei Scherbakov
> Assignee: Denis Chudov
> Priority: Major
> Fix For: 2.8
>
> Time Spent: 1h 40m
> Remaining Estimate: 0h
>
> With large topology and large amount of caches/partitions and enabled
> persistence could be millions of FilePageStore objects in heap (for each
> partition).
> Each instance has a reference to a File (field cfgFile) storing as String
> absolute path to a partition.
> Also internal File inplementation (on example UnixFile) also allocates space
> for file path.
> I observed about 2Gb of heap space occupied by these objects in one of
> environments.
> Solution: dereference (set to null) cfgFile after object creation, create
> File object lazily on demand when needed.
