    [ https://issues.apache.org/jira/browse/HBASE-5612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13401108#comment-13401108 ] 

alex gemini commented on HBASE-5612:
------------------------------------

for the filter, if we know the data types,we can use more meaningful comparison filter for column name to filter out more data in LESS filter and GREATER filter.

> In many real-life applications all values in a certain column family are of a certain data type, e.g. 64-bit integer. We could specify that in the column descriptor and enable data type-specific compression such as variable-length integer encoding.
