-----------------------------------
Summary: Add a option to disable the data block cache for testing
the performance of underlying file system
Key: HBASE-15338
URL: https://issues.apache.org/jira/browse/HBASE-15338
Project: HBase
Issue Type: Improvement
Components: integration tests
Reporter: Liu Shaohui
Assignee: Liu Shaohui
When testing and comparing the performance of different file systems(HDFS,
Azure blob storage, AWS S3 and so on) for HBase, it's better to avoid the
affect of the HBase BlockCache and get the actually random read latency when
data block is read from underlying file system. (Usually, the index block and
meta block should be cached in memory in the testing).
So we add a option in CacheConfig to disable the data block cache.
Suggestions are welcomed~ Thanks
