Subject [jira] [Commented] (HBASE-7949) Enable big content store in HBase
Date Fri, 08 Mar 2013 11:02:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7949?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13597018#comment-13597018

chenning commented on HBASE-7949:
---------------------------------

The solution makes sensen to me if the content is not big enough. I am curious on the  performance
of the split, how long the region can be splitted, my understanding the lob family should
participate the region split, and  the region is unavailable during this period.

> Big content stored in hbase consumes a lot of system resource when region split or compaction
operation happens.
> How HBase can be used to store big content along with some self descriptive meta-data.

> The general idea is to add a new type of column family, and the content of this kind
of column family doesn't participate the region split and compaction. An index(rowkey-location)
is introduced in this new column family and the split and compaction are only applied to this
index.
