Vladimir Rodionov updated HBASE-30022:
--------------------------------------
Description:
h2. Description
Refactor *HFileReaderImpl* and *CacheConfig* to use *CacheAccessService* as
the entry point for block cache access instead of directly interacting with
*BlockCache*.
This change updates the read path to delegate cache operations through
CacheAccessService, including:
* block lookup on read
* cache population on read miss
* cache-related metrics updates (if applicable)
h3. Scope
* Replace direct BlockCache calls in *HFileReaderImpl* with *CacheAccessService*
* Enhance *CacheConfig* API to access *CacheAccessService* instance
* Adapt existing call parameters to use request/write context objects
* Ensure compatibility with current caching behavior
h3. Notes
* No behavior change intended
* Existing cache implementations (*LruBlockCache*, *BucketCache*,
*CombinedBlockCache*) remain unchanged
* CacheAccessService implementation continues to delegate to BlockCache in this
phase
* This is part of migrating read path code toward a pluggable cache architecture
