Data is captured and stored for a variety of reasons. Hours beyond count (and even more budget) invested in collecting, ingesting, structuring, validating, and ultimately storing of data; to say that it is a valuable asset is to drive home a moot point. This day in age it may, in fact, be our most precious commodity.

Some data is used strictly as an archive. Perhaps to record or track events that happened in the past. But the other side of that coin is that historical data has value in basing decisions for the future and future endeavors.

• What day to have our sale on? (Planning for future sales based on how we did in the past.)
• Which salesperson performed the best in quarter one? (Looking back, who can we reward for their efforts.)
• Which restaurant is frequented the most in the middle of July? (The travel season is upon us... Who can we sell our foodstuffs and goods to?)

Last week I came across a bug in MySQL 8.0, which meant that the absence of mysql.user leads to auto-apply of –skip-grant-tables (#94394) would leave MySQL running in an undesirable state. My colleague Sveta Smirnova blogged about the issue and it also caught the interest of Valeriy Kravchuk in Fun with Bugs #80 – On MySQL Bug Reports I am Subscribed to, Part XVI. Thanks for the extra visibility!

Credit is now due to Oracle for the quick response, as it was fixed in less than one week (including a weekend):

Fixed in 8.0.16.

Previously, if the grant tables were corrupted, the MySQL server

InnoDB keeps hot data in memory on its buffer named InnoDB Buffer Pool. For a long time, when a MySQL instance needed to bounce, this hot cached data was lost and the instance required a warm-up period to perform as well as it did before the service restart.

That is not the case anymore. Newer versions of MySQL/MariaDB allow users to save the state of this buffer by dumping tablespace ID’s and page ID’s to a file on disk that will be loaded automatically on startup, making the newly started server buffer pool as it was prior the restart.

Details about the MySQL implementation can be found at https://dev.mysql.com/doc/refman/5.7/en/innodb-preload-buffer-pool.html

With that in mind, Percona XtraBackup versions …
