MySQL Error 3570: Unsafe SKIP LOCKED Statement
Description
This error occurs when a SQL statement using `SKIP LOCKED` is deemed unsafe for binary logging and potential replication. It signifies that the operation might produce different results on a replica server, leading to data inconsistency.
Error Message
Statement is unsafe because it uses SKIP LOCKED. The set of inserted values is non-deterministic.
Known Causes
3 known causesNon-Deterministic `SKIP LOCKED`
The `SKIP LOCKED` clause introduces non-deterministic behavior, making the statement unsuitable for `STATEMENT` or `MIXED` binary logging formats.
Implicit Writes with `SKIP LOCKED`
Combining `SKIP LOCKED` with statements that implicitly write data (e.g., `INSERT ... SELECT`) makes the set of affected rows non-deterministic for the binary log.
Incompatible Binlog Format
The current `binlog_format` setting (e.g., `STATEMENT` or `MIXED`) is incompatible with the non-deterministic nature of `SKIP LOCKED` operations.
