UPDATE_TIME for InnoDB in MySQL 5.7

0 votes
600 views

The MySQL 5.7 changelog mentions:
"Beginning with MySQL 5.7.2, UPDATE_TIME displays a timestamp value for the last UPDATE, INSERT, or DELETE performed on InnoDB tables. Previously, UPDATE_TIME displayed a NULL value for InnoDB tables. For MVCC, the timestamp value reflects the COMMIT time, which is considered the last update time. Timestamps are not persisted when the server is restarted or when the table is evicted from the InnoDB data dictionary cache."

This is great news! However, I would in fact need the UPDATE_TIME to persist across database server resets. Is this feature being considered or discussed? Where might I find it online?

Yeah, why not flush them to disk on a clean shutdown, and periodically before that?

Optimizing InnoDB tables in MySQL?

I was trying to optimize the InnoDB tables. I have executed the next query to detect what are the fragmented tables.

SELECT TABLE_SCHEMA,TABLE_NAME
FROM TABLES WHERE TABLE_SCHEMA NOT IN ("information_schema","mysql") AND Data_free > 0

After that, I have seen that there are 49 fragmented tables. With one table, I have executed "optimize table table_name;" and "analyze table table_name;". The result is the same, the table continuous fragmented.

Any suggestions? I have followed the mysqltuner recommendations...

Mysql Innodb Performance - How to minimise multicolumn index?

Below table contains billion of rows,

CREATE TABLE `Sample1` (
  `c1` bigint(20) NOT NULL AUTO_INCREMENT,
  `c2` varchar(45) NOT NULL,
  `c3` tinyint(4) DEFAULT NULL,
  `c4` tinyint(4) DEFAULT NULL,
  `time` bigint(20) DEFAULT NULL,
  PRIMARY KEY (`c1`),
  KEY `varchar_time_idx` (`c2`,`Time`),
  KEY `varchar_c3_time_idx` (`c2`,`c3`,`Time`),
  KEY `varchar_c4_time_idx` (`c2`,`c4`,`Time`),
  KEY `varchar_c3_c4_time_idx` (`c2`,'c3', `c4`,`Time`),
) ENGINE=InnoDB AUTO_INCREMENT=10093495 DEFAULT CHARSET=utf8

Four multi column index created because having below conditions in where

1) c2 and time
2) c2 and c3 and time
3) c2 and c4 and time
4) c2 and c3 and c4 and time

Cardinality wise c2, c3 and c4 are very low. (ex: Out of one million c2, c3 and c4 have 50 unique column in each)

Column time contains mostly unique fields.

Select, insert and update happened frequently.

Tables has 5 indexing fields(4 multi column). Due to this, 1) Insert and update on index fields become costlier. 2) As the table keep on growing (Nearly one billion rows), Index size also increase more rapidly.

Kindly suggest good approach in mysql to solve this use case.

InnoDB problem on MySQL - table does not exist

I've restored an MySQL backup from our MySQL server into another server. The backup includes InnoDB tables. After the import, MySQL recognized the innodb tables fine but when I try to do a check table it returns that the table doesn't exists.

Permission and owner of the table files (.frm files) are ok, since it recognizes MyISAM tables (they have the same permission). Innodb engine is enabled..

Which can cause the tables to appears as "non existent", as far as they do really exist?
