Subject [jira] [Commented] (HBASE-15314) Allow more than one backing file in bucketcache
Date Fri, 24 Feb 2017 02:57:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15314?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15881836#comment-15881836
] 

chunhui shen commented on HBASE-15314:
--------------------------------------

bq. How would you handle the case of striping
Read the block from two files if crossed, just like the handling of ByteBufferIOEngine which
would read block from multiple ByteBuffer.
This logic is implemented  by FileIOEngine#accessFile from the attachment 'FileIOEngine.java'.


Thanks

SSD in it.
