PlanetScale introduces Rewind feature to ‘undo’ bad schema migrations

PlanetScale is including a Rewind attribute to its serverless MySQL databases-as-a-company, allowing buyers to ‘revert changes’ up to 30 minutes after a schema migration deployment request is designed.

PlanetScale would like to support databases directors or devops professionals to very easily ‘undo’ undesirable schema migrations before, with out the pain of manually rolling back and resulting in downtime or information decline challenges for the business.

“PlanetScale Rewind offers people the skill to undo a lousy migration just as very easily as you undo a typo,” claimed Nick Van Wiggeren, vice president of engineering at PlanetScale. “Instead of owning to go restart the total process, envision if you could just simply click a button — like Control-Z — and get it back again to the place it was when you begun but, notably, without the need of losing a byte of facts.”

Whilst other database-as-a-company vendors have presented customers the capacity to revert to a snapshot, which commonly entailed losing some details during the deployment or migration approach, PlanetScale statements its Rewind attribute is an business first because of to the speed at which consumers can reverse variations devoid of shedding knowledge.

The feature is powered by VReplication, a indigenous capability of the open up resource clustering and management technique Vitess, which underpins the PlanetScale database and which allows faster migrations and consequently more quickly rollbacks as needed.

“VReplication can be set up to migrate information from an existing system into Vitess. The replication could also be reversed immediately after a cutover offering you the possibility to rollback a migration cutover if some thing went erroneous, devoid of dropping the writes to the migration goal,” a Vitess weblog publish claims.

PlanetScale refers to itself as “the databases for developers,” and Stephen O’Grady, principal analyst at developer-focused analyst company RedMonk, mentioned that, “what PlanetScale is announcing nowadays is aimed at executing just that: improving upon the developer practical experience of making use of a database.”
