Vladimir Rodionov updated HBASE-30023:
--------------------------------------
Description:
Description
Refactor write path, prefetch, and compaction-related cache population to use
CacheAccessService instead of directly interacting with BlockCache.
This change updates all non-read-path cache interactions to go through
CacheAccessService, including:
• cache-on-write in HFileWriter
• prefetch-related cache population
• compaction-related cache population
• block invalidation triggered during file lifecycle events
Scope
• Replace direct BlockCache calls in:
• HFile write path
• prefetch logic
• compaction workflows
• Route all cache population and invalidation operations through
CacheAccessService
• Adapt existing parameters to use write and invalidation context
objects
Notes
• No behavior change intended
• Existing cache implementations (LruBlockCache, BucketCache,
CombinedBlockCache) remain unchanged
• CacheAccessService continues to delegate to BlockCache in this
phase
• Complements read-path migration by ensuring all cache
interactions go through a unified abstraction
was:
Adapt BucketCache to the new BlockCacheEngine interface.
Ensure compatibility with:
• async write path (RAM queue, writer threads)
• persistence/backing map
• eviction and stats behavior
• file-based invalidation
No functional changes expected.
