## 3.2. Isolation levels

By default a read operation will read the last committed value unless a local modification within the current transaction exist. The default isolation level is very similar to `READ_COMMITTED`: reads do not block or take any locks so non-repeatable reads can occur. It is possible to achieve a stronger isolation level (such as `REPETABLE_READ` and `SERIALIZABLE`) by manually acquiring read and write locks.
