MySQL Error 1672: Unsafe UDF Replication
Description
Error 1672 indicates that a SQL statement using a User-Defined Function (UDF) is considered unsafe for statement-based replication. This occurs when MySQL determines the UDF might produce different results on the source and replica servers, leading to data inconsistency.
Error Message
Statement is unsafe because it uses a UDF which may not return the same value on the replica.
Known Causes
4 known causesNon-Deterministic UDF Usage
The UDF used in the statement produces varying results each time it's called or depending on the server's state, making it unsuitable for consistent statement-based replication.
UDF Relies on Local Server State
The UDF's logic incorporates server-specific configurations, file paths, or other non-replicated information, causing potential divergence on the replica.
Incompatible Replication Mode
The current statement-based replication (SBR) mode is not suitable for replicating statements that utilize UDFs with non-deterministic behavior or server-specific dependencies.
UDF Not Present on Replica
The User-Defined Function executed on the source server does not exist or is not correctly defined on the replica, preventing consistent execution of the statement.
