chenning commented on HBASE-7949:
---------------------------------
[~maryannxue]thanks for the sides on this issue.
I have one question -- why the content for lob family still goes into memstore
and flushed into HDFS? Since I think the content will occupy more memory and
result in more frequent flushes and minor compactions?
My idea is to persisted the content directly into HDFS, but maybe this will
involve more complexities in regionserver to handle the consistency, the
orphans, and row atomic etc.

> 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.
