Lars Hofhansl commented on HBASE-11339:
---------------------------------------
Is it better to store small blobs (let's say 1mb or less) in HBase (by value)
and larger blob directly in files in HDFS with just a reference in HBase?
Writing large blobs would be a three step process: (1) add the metadata to
HBase (2) stream the actual blob into HDFS (3) set a "written" column in the
HBase row to true.
Just saying... That way it could be handled by client alone.

> It's quite useful to save the massive binary data like images, documents
> into Apache HBase. Unfortunately directly saving the binary LOB(large object)
> to HBase leads to a worse performance since the frequent split and compaction.
> In this design, the LOB data are stored in an more efficient way, which
> keeps a high write/read performance and guarantees the data consistency in
> Apache HBase.
