    [ https://issues.apache.org/jira/browse/HBASE-13122?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14343269#comment-14343269 ] 

Shuaifeng Zhou commented on HBASE-13122:
----------------------------------------

We have done a performance test, here are the result:
FamilyFilter:
test table have two familys , each have 3 qualifier, and put 10000 rows into the table, each row&qualifier have 1000 versions.
scan use familyFilter get values from the second family, scaned 2000 rows and 100 versions of each row& qualifier.
Use the oraginal FamilyFilter, cost average 309 seconds, but with the improved familyFilter, the cost is average 38 seconds, improved about 700%
ColumnRangeFilter:
The same data but only one family, scan 10000 rows and 1000 versions, orangial cost average 68s, the improved cost 64s, improved a little. 
Because in the FamilyFilter, the improve will reduce read files, so improved significantly, but the columnRangeFilter can not reduce read files, so imporve little.

> ColumnRangeFilter:
>  when minColumnInclusive is false, it means all the cells at the current row&column not fit the condition, so it should skip to next column, return code should be NEXT_COL, not SKIP.
> FamilyFilter is the similar sitution.
> Currently, SKIP will not causing error, but not efficent.
