MySQL Error 3571: Statement uses NOWAIT unsafely
Description
Error 3571 occurs when a SQL statement includes the `NOWAIT` clause, making its success or failure non-deterministic. MySQL flags such statements as 'unsafe' for binary logging, as their unpredictable outcome can lead to replication inconsistencies.
Error Message
Statement is unsafe because it uses NOWAIT. Whether the command will succeed or fail is not deterministic.
Known Causes
3 known causesInclusion of NOWAIT Clause
The problematic SQL statement explicitly uses the `NOWAIT` clause, which prevents it from waiting for locks and can lead to immediate failure.
Binary Logging Enabled
The MySQL server has binary logging enabled, making the non-deterministic nature of `NOWAIT` statements a concern for replication safety.
Non-Deterministic Statement Outcome
The `NOWAIT` clause can cause a statement's execution outcome (success/failure) to vary depending on momentary lock availability, which is problematic for consistent replication.
