Sergey Soldatov updated PHOENIX-2845:
-------------------------------------
Attachment: PHOENIX-2845-1.patch
We are using joda-time to parse all date/time related expressions which doesn't
support nanos. As an workaround we can get nanos by parsing string using
Timestamp.valueOf. It doesn't look like a perfect solution since we have to
parse the string two times. As an alternative approach we can do parsing
everything after the dot ourself.
> Timestamp ignores nanos in literal expressions

> Phoenix strips nanos in Timestamp. Simple test case:
> {noformat}
> create table x (id bigint primary key, t timestamp);
> upsert into x values (1, TIMESTAMP'2015-01-01 00:00:00.123456');
> upsert into x values (2, TIMESTAMP'2015-01-01 00:00:00.123457');
> upsert into x values (3, TIMESTAMP'2015-01-01 00:00:00.123999');
> {noformat}
> HBase scan:
> {noformat}
> hbase(main):007:0> scan 'X'
> ROW COLUMN+CELL
> \x80\x00\x00\x00\x00\x00\x00\x01 column=0:T, timestamp=1460646668779,
> value=\x80\x00\x01J\xA2\xCA\xB0{\x00\x00\x00\x00
> \x80\x00\x00\x00\x00\x00\x00\x02 column=0:T, timestamp=1460646673369,
> value=\x80\x00\x01J\xA2\xCA\xB0{\x00\x00\x00\x00
> \x80\x00\x00\x00\x00\x00\x00\x03 column=0:T, timestamp=1460646680294,
> value=\x80\x00\x01J\xA2\xCA\xB0{\x00\x00\x00\x00
