IsolationLevel enum

The isolation level of a transaction determines what data the transaction can see when other transactions are running concurrently.

Inheritance

Values

readCommitted → const IsolationLevel: A statement can only see rows committed before it began. This is the default.

const IsolationLevel._('READ COMMITTED')
repeatableRead → const IsolationLevel: All statements of the current transaction can only see rows committed before the first query or data-modification statement was executed in this transaction.

const IsolationLevel._('REPEATABLE READ')
serializable → const IsolationLevel: All statements of the current transaction can only see rows committed before the first query or data-modification statement was executed in this transaction. If a pattern of reads and writes among concurrent serializable transactions would create a situation which could not have occurred for any serial (one-at-a-time) execution of those transactions, one of them will be rolled back with a serialization_failure error.

const IsolationLevel._('SERIALIZABLE')
readUncommitted → const IsolationLevel: One transaction may see uncommitted changes made by some other transaction. In PostgreSQL READ UNCOMMITTED is treated as READ COMMITTED.

const IsolationLevel._('READ UNCOMMITTED')
