Jonathan Hsieh updated HBASE-11339:
-----------------------------------
    Release Note: 
The Moderate Object Storage (MOB) feature (HBASE-11339[1]) is modified I/O and 
compaction path that allows individual moderately sized values (100KB-10MB) to 
be stored in a way that write amplification is reduced when compared to the 
normal I/O path. MOB is defined in the column family and it is almost isolated 
with other components, the features and performance cannot be effected in 
normal columns.

For more details on how to use the feature please consult the HBase Reference 
Guide

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