rotate table partition for MySQL

Getting Started

Hourly rotate mode

First you must create the table

CREATE TABLE `test_rotate_hourly` (
  `dt` datetime NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1
 PARTITION BY RANGE (TO_SECONDS(dt))
(PARTITION `start` VALUES LESS THAN (0) ,
PARTITION from2020100322 VALUES LESS THAN (TO_SECONDS('2020-10-03 23:00:00')) ,
PARTITION from2020100323 VALUES LESS THAN (TO_SECONDS('2020-10-04 00:00:00')) ,
PARTITION from2020100400 VALUES LESS THAN (TO_SECONDS('2020-10-04 01:00:00')) ,
PARTITION from2020100401 VALUES LESS THAN (TO_SECONDS('2020-10-04 02:00:00')) ,
PARTITION from2020100402 VALUES LESS THAN (TO_SECONDS('2020-10-04 03:00:00')) ,
PARTITION from2020100403 VALUES LESS THAN (TO_SECONDS('2020-10-04 04:00:00')) ,
PARTITION future VALUES LESS THAN MAXVALUE )

Then you can start rotating the table

<?php
use Jinraynor1\PartitionRotator\RotateModeHourly;
use Jinraynor1\PartitionRotator\PartitionRotator;

$username = "root";
$password = "";
$db = new PDO("mysql:host=localhost;dbname=testdb",$username,$password);
$database_name ="testdb";
$table_name = "test_rotate_hourly";
$oldest_partition = new DateTime(6 hour ago");
$newest_partition = new DateTime("now");
$rotate_mode = new RotateModeHourly();

$partition = new PartitionRotator($db, $database_name, $table_name, $oldest_partition, $newest_partition, $rotate_mode);
$partition->rotate();

Daily rotate mode

First you must create the table

CREATE TABLE table_rotate_daily (
dt datetime NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1
PARTITION BY RANGE (TO_DAYS(dt))
(PARTITION start VALUES LESS THAN (0) ,
PARTITION from20201002 VALUES LESS THAN (TO_DAYS('2020-10-03')) ,
PARTITION from20201003 VALUES LESS THAN (TO_DAYS('2020-10-04')) ,
PARTITION from20201004 VALUES LESS THAN (TO_DAYS('2020-10-05')) ,
PARTITION from20201005 VALUES LESS THAN (TO_DAYS('2020-10-06')) ,
PARTITION from20201006 VALUES LESS THAN (TO_DAYS('2020-10-07')) ,
PARTITION from20201007 VALUES LESS THAN (TO_DAYS('2020-10-08')) ,
PARTITION future VALUES LESS THAN MAXVALUE ) 

Then you can start rotating the table

<?php
use Jinraynor1\PartitionRotator\RotateModeDaily;
use Jinraynor1\PartitionRotator\PartitionRotator;

$username = "root";
$password = "";
$db = new PDO("mysql:host=localhost;dbname=testdb",$username,$password);
$database_name ="testdb";
$table_name = "table_rotate_daily";
$oldest_partition = new DateTime("1 week ago");
$newest_partition = new DateTime("today");
$rotate_mode = new RotateModeDaily();
            
$partition = new PartitionRotator($db, $database_name, $table_name, $oldest_partition, $newest_partition, $rotate_mode);
$partition->rotate();

Monthly rotate mode

CREATE TABLE table_rotate_monthly (
dt DATETIME NOT NULL
) ENGINE=MYISAM DEFAULT CHARSET=latin1
PARTITION BY RANGE (TO_DAYS(dt))
(PARTITION start VALUES LESS THAN (0) ,
PARTITION from202010 VALUES LESS THAN (TO_DAYS('2020-11-01')) ,
PARTITION from202011 VALUES LESS THAN (TO_DAYS('2020-12-01')) ,
PARTITION from202012 VALUES LESS THAN (TO_DAYS('2021-01-01')) ,
PARTITION from202101 VALUES LESS THAN (TO_DAYS('2020-02-01')) ,
PARTITION future VALUES LESS THAN MAXVALUE )

use Jinraynor1\PartitionRotator\RotateModeMonthly;
use Jinraynor1\PartitionRotator\PartitionRotator;

$username = "root";
$password = "";
$db = new PDO("mysql:host=localhost;dbname=testdb",$username,$password);
$database_name ="testdb";
$table_name = "table_rotate_monthly";
$oldest_partition = new DateTime("1 year ago");
$newest_partition = new DateTime("today");
$rotate_mode = new RotateModeMonthly();
            
$partition = new PartitionRotator($db, $database_name, $table_name, $oldest_partition, $newest_partition, $rotate_mode);
$partition->rotate();
