Liu Shaohui updated HBASE-15338: -------------------------------- Attachment: HBASE-15338-trunk-v4.diff Update the patch ~ Thanks for [~jingcheng...@intel.com] and [~anoop.hbase]. > 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 > Priority: Minor > Fix For: 2.0.0 > > Attachments: HBASE-15338-trunk-v1.diff, HBASE-15338-trunk-v2.diff, > HBASE-15338-trunk-v3.diff, HBASE-15338-trunk-v4.diff > > > 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
