Hello,
I am a developer who implement big-data infra-system using phoenix.
Our team want to make a built-in-function ABS(absolute function)
We made it and it works good but not work order by clause.
We can't find where is the place executing order by function.
ex)
here is the test table, table has 2 rows like below.
create table test (a integer not null primary key, b varchar(10));
a b
2 abc
-1 ab
ex) select abs(a), b from test ;
2 abc
1 ab
works fine. good. but .....
ex) select abs(a),b from test order by abs(a);
2 abc
1 ab
not working....
Question)
Where is the place to execute order by expression? in phoenix client? or
hbase co-processor?
Could you please tell me the point or class name or method name that we
have to implement?
we are working on phoenix-2.2.4 version.
Please answer me.
Thanks in advance.
