[jira] [Comment Edited] (HBASE-11339) HBase MOB

    [ https://issues.apache.org/jira/browse/HBASE-11339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14115526#comment-14115526 ]

[~jiajia], new version of docs look good, I think it is done for now unless we make changes to it. 

nits: I found there are two typos,  "provinding" \-> "providing" and "handers"\->"handlers".    Don't worry about fixing this for now -- we'll have [~misty] convert them into a chapter or section in the ref guide.

Also, in the future, please do not delete attachments -- just provide a new version with a v2 or some think like that so we can keep track of the evolution.

>   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.
