Subject [jira] [Commented] (HBASE-9247) Cleanup Key/KV/Meta/MetaKey Comparators
Date Mon, 19 Aug 2013 15:36:50 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9247?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13743908#comment-13743908
] 

stack commented on HBASE-9247:
------------------------------

bq. Why is the Comparator serialized into part of the HFile?

Long time ago, it 'made sense' that we note the comparator used writing the file so the reader
used same.

bq. Beyond Meta Key and a normal Key, is there external uses of his that I'm not aware of
that I may break? (Phoenix?)

No.  Way too exotic for outside clients to even know this facility even existed.

> HBASE-9164 converted KVComparator's KeyCompare#compare guts from one that assumed a contiguous
array backing a KV to one that used the Cell interface which doesn't have this assumption.
> There is now duplicate code that should be cleaned up.
