Serializable Isolation

What is Serializable Isolation?

Serializable Isolation is the highest level of isolation possible under the guidelines provided by the “ANSI SQL Standard” (an official standard of best SQL practices). It means that transactions committed to a database appear as if they were executed one after another, even if they were processed in parallel. Most distributed databases only achieve a lower level of isolation, called “snapshot isolation,” but CockroachDB is able to achieve serializable isolation.
