Chia-Ping Tsai updated HBASE-18742:
-----------------------------------
Description:
I'm profiling phoenix query w/wo hbase cache. And then i noticed the following
codes in CacheConfig.
{code}
this(CacheConfig.instantiateBlockCache(conf),
conf.getBoolean(CACHE_DATA_ON_READ_KEY, DEFAULT_CACHE_DATA_ON_READ)
&& family.isBlockCacheEnabled(),
family.isInMemory(),
// For the following flags we enable them regardless of per-schema
settings
// if they are enabled in the global configuration.
conf.getBoolean(CACHE_BLOCKS_ON_WRITE_KEY,
DEFAULT_CACHE_DATA_ON_WRITE) || family.isCacheDataOnWrite(),
conf.getBoolean(CACHE_INDEX_BLOCKS_ON_WRITE_KEY,
DEFAULT_CACHE_INDEXES_ON_WRITE) || family.isCacheIndexesOnWrite(),
conf.getBoolean(CACHE_BLOOM_BLOCKS_ON_WRITE_KEY,
DEFAULT_CACHE_BLOOMS_ON_WRITE) || family.isCacheBloomsOnWrite(),
conf.getBoolean(EVICT_BLOCKS_ON_CLOSE_KEY,
DEFAULT_EVICT_ON_CLOSE) || family.isEvictBlocksOnClose(),
conf.getBoolean(CACHE_DATA_BLOCKS_COMPRESSED_KEY,
DEFAULT_CACHE_DATA_COMPRESSED),
conf.getBoolean(PREFETCH_BLOCKS_ON_OPEN_KEY,
DEFAULT_PREFETCH_ON_OPEN) || family.isPrefetchBlocksOnOpen(),
conf.getBoolean(ColumnFamilyDescriptorBuilder.CACHE_DATA_IN_L1,
ColumnFamilyDescriptorBuilder.DEFAULT_CACHE_DATA_IN_L1) ||
family.isCacheDataInL1(),
conf.getBoolean(DROP_BEHIND_CACHE_COMPACTION_KEY,
DROP_BEHIND_CACHE_COMPACTION_DEFAULT)
);
{code}
The global configuration for cache do NOT look like global switch. The codes
should be like this.
{code}
config.get(xxx, family.isxxx)
{code}
The cf level config should honor the global config.
