Ignite TC Bot updated IGNITE-26973:
-----------------------------------
Ignite Flags: (was: Release Notes Required)
> IndexProcessor: ConcurrentHashMap under RW-lock; reconsider redundant idxDefs
> map
> ---------------------------------------------------------------------------------
>
> Key: IGNITE-26973
> URL: https://issues.apache.org/jira/browse/IGNITE-26973
> Project: Ignite
> Issue Type: Improvement
> Reporter: Vsevolod Kovalev
> Assignee: Vsevolod Kovalev
> Priority: Major
> Fix For: 2.18
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> {{_*IndexProcessor*_}} guards access with a {_}{{ReentrantReadWriteLock}}{_},
> yet both {{_cacheToIdx_}} and {{_idxDefs_}} are {{{}_ConcurrentHashMap_{}}}.
> This likely adds overhead without benefit.
> Additionally, {{_idxDefs_}} ({{{}_UUID → IndexDefinition_{}}}) appears
> redundant because Index already holds its {{_IndexDefinition_}} and exposes
> the {{{}_UUID_{}}}.
> *Action items:*
> * Audit read/write paths to confirm lock coverage.
> * If confirmed, replace both with plain HashMap.
> * Evaluate removing idxDefs in favor of retrieving IndexDefinition from
> Index; refactor call sites if feasible.
