This commit adds configuration options to control how RocksDB handles index and filter blocks in the block cache: - kv.rocksdb.block.cache-index-and-filter-blocks: Store index/filter blocks in block cache to limit memory usage (default: false) - kv.rocksdb.block.cache-index-and-filter-blocks-with-high-priority: Give index/filter blocks high priority in cache (default: false) - kv.rocksdb.block.pin-l0-filter-and-index-blocks-in-cache: Pin L0 index/filter blocks to avoid eviction (default: false) - kv.rocksdb.block.pin-top-level-index-and-filter: Pin top-level partitioned index/filter blocks (default: false) These options help users control RocksDB memory usage by allowing index and filter blocks to be managed within the block cache, preventing unbounded memory growth.
