MySQL Error 3932: Function Key Length Exceeded
Description
This error indicates that a User-Defined Function (UDF) encountered an issue where a provided key, identifier, or parameter exceeded its maximum allowed length. This typically occurs when the UDF interacts with a keyring plugin or has internal constraints on input sizes.
Error Message
Function '%s' failed because key length is too long.
Known Causes
4 known causesUDF Parameter Length Exceeded
A parameter or argument passed to the User-Defined Function (UDF) is longer than the maximum length the function or its underlying logic can process.
Keyring Plugin Key Length Limit
If the UDF interacts with a MySQL Keyring plugin (e.g., for encryption/decryption or secret storage), the key it attempts to use or manage is longer than the keyring's configured limit.
Incorrect UDF Definition
The User-Defined Function might have been defined or registered with an expectation of shorter input lengths, leading to failures when longer values are supplied.
External Data Key Mismatch
Data originating from an external application or system contains keys or identifiers that are valid in their original context but exceed the length limits enforced by the MySQL UDF or keyring.
