method Deno.Kv.prototype.atomic
Kv.prototype.atomic(): AtomicOperation
Create a new [`Deno.AtomicOperation`](../././~/Deno.AtomicOperation) object which can be used to
perform an atomic transaction on the database. This does not perform any
operations on the database - the atomic transaction must be committed
explicitly using the `Deno.AtomicOperation.commit` method once
all checks and mutations have been added to the operation.
