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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
