- 년도를 기준으로 파티셔닝 (new 게시물 갯수가 많은 경우는 월별/일별로 파티셔닝)

1. g4_board_new 테이블의 record 갯수와 가장 오래된 dn_datetime을 확인

있는 날짜부터 파티셔닝을 하면 되니까...

2. table structure를 확인

primary key를 확인. 그누보드 기본은 bd_id 입니다.

3. bn_datetime을 primary key에 추가

파티셔닝의 기준이 되는 날짜가 primary key에 들어 있어야 합니다.

ALTER TABLE `g4_board_new` DROP PRIMARY KEY ,
ADD PRIMARY KEY ( `bn_id` , `bn_datetime` )

4. SQL script를 작성

ALTER TABLE g4_board_new
PARTITION BY RANGE ( TO_DAYS(bn_datetime) ) (
PARTITION new2007 VALUES LESS THAN (TO_DAYS('2008-01-01')),
PARTITION new2008 VALUES LESS THAN (TO_DAYS('2009-01-01')),
