>   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.
