Subject [jira] [Updated] (HBASE-7949) Enable big content store in HBase
Date Thu, 07 Mar 2013 03:36:15 GMT

Maryann Xue updated HBASE-7949:
-------------------------------

    Attachment: HBase_LOB.pdf

At the recent hbase meetup, we just gave an introduction of an implementation for storing
large objects.
The idea is to store the real content onto HDFS and let customized major compaction for this
family handle the management work for these large contents.
And we need a customizable flush() process for this approach.

> 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.
