Zheng Hu commented on HBASE-20151:
----------------------------------
[[email protected]] Skimmed the patch, so the patch still adjust the upper
layer only for the special FamilyFilter ? IMO, we may not need that.. I mean
if someone want better performance, can just create an new filter named
FamilyAloneFilter (or some other name) , which inherit the FamilyFilter and
override the filterCell() method ...
Or we can provide two FamilyFilter(one for skip, or one for next_row, and give
a javadoc said that the next_row can not used in FL) in the official repo ?

> When running the following queries, the result is sometimes return correctly
> and other times incorrectly based on the qualifier queried.
> Setup:
> {code:java}
> create 'test', 'a', 'b'
> test = get_table 'test'
> test.put '1', 'a:1', nil
> test.put '1', 'a:10', nil
> test.put '1', 'b:2', nil
> {code}
>
> This query works fine when the SCVF's qualifier has length 1 (i.e. '1') :
> {code:java}
> test.scan({ FILTER => "(
> SingleColumnValueFilter('a','1',=,'binary:',true,true) AND
> FamilyFilter(=,'binary:b') )"})
> ROW COLUMN+CELL
> 1 column=b:2,
> timestamp=1520455888059, value=
> 1 row(s) in 0.0060 seconds
> {code}
>
> The query should return the same result when passed a qualifier of length 2
> (i.e. '10') :
> {code:java}
> test.scan({ FILTER => "(
> SingleColumnValueFilter('a','10',=,'binary:',true,true) AND
> FamilyFilter(=,'binary:b') )"})
> ROW COLUMN+CELL
> 0 row(s) in 0.0110 seconds
> {code}
> However, in this case, it does not return any row (expected result would be
> to return the same result as the first query).
>
> Removing the family filter while the qualifier is '10' yields expected
> results:
> {code:java}
> test.scan({ FILTER => "(
> SingleColumnValueFilter('a','10',=,'binary:',true,true) )"})
> ROW COLUMN+CELL
> 1 column=a:1,
> timestamp=1520455887954, value=
> 1 column=a:10,
> timestamp=1520455888024, value=
> 1 column=b:2,
> timestamp=1520455888059, value=
> 1 row(s) in 0.0140 seconds
> {code}
