Re: ERROR 1025 (HY000): Error on rename of '.\reporting\#sql-a2c_1' to '.\reporting\event' (errno: -1)

[Raghavendra K]

Below is the SELECT Query

SELECT `event`.`time`, `model`.`model_name`, `model`.`network_address`, `creator`.`creator_name`, `event`.`
ype`, `event`.`event_key`, `v_security_string_accessibility_by_landscape`.`user_name`, `event`.`event_msg` FROM ((`reporting`.`event` `event` INNER JOIN `reporting`.`model` `model` ON `event`.`model_key`=`model`.`mode
_key`) INNER JOIN `reporting`.`creator` `creator` ON `event`.`creator_id`=`creator`.`creator_ID`) INNER JOIN `reporting`.`v_security_string_accessibility_by_landscape` `v_security_string_accessibility_by_landscape` ON (
model`.`landscape_h`=`v_security_string_accessibility_by_landscape`.`landscape_h`) AND (`model`.`security_string`=`v_security_string_accessibility_by_landscape`.`security_string`) WHERE (`event`.`time`>='2013-12-10 00:
1:00' AND `event`.`time`<'2013-12-10 23:59:01') AND `v_security_string_accessibility_by_landscape`.`user_name`='ad_knatan' ORDER BY `event`.`time` DESC


Many tables were been involved in this query. All table records are less than 10Million except 'event' table which has 500 Million records and keep on grows


Regarding partitions (p1, p2, p3) which got failed. I tried with two partitions and got success

mysql> ALTER TABLE event PARTITION BY RANGE COLUMNS(time) (
-> PARTITION p1 VALUES LESS THAN ('2013-12-08'),
-> PARTITION p2 VALUES LESS THAN MAXVALUE );
Query OK, 442981556 rows affected (2 days 23 hours 38 min 8.33 sec)
Records: 442981556 Duplicates: 0 Warnings: 0

is there a way to increase the execution speed? current its taking almost 3 days for 2 partitions.
