MySQL Error 3957: Clone Packet Size Mismatch
Description
This error occurs during a MySQL Clone operation when the `max_allowed_packet` system variable on the recipient server is set to a value lower than what is required for the cloning process. The clone operation transfers data in packets, and if the maximum allowed packet size is insufficient, the operation fails.
Error Message
Clone needs max_allowed_packet value to be %u or more. Current value is %u
Known Causes
3 known causesRecipient max_allowed_packet Too Low
The `max_allowed_packet` server variable on the recipient server is configured with a value that is less than the minimum required for the MySQL Clone operation to succeed.
Default Configuration Insufficiency
The default `max_allowed_packet` value, often 4MB, may not be sufficient for cloning operations involving large datasets or specific configurations, requiring a higher value.
Large Data Transfer Requirements
Cloning large databases or complex schemas often requires significantly larger packet sizes to efficiently transfer all data, exceeding the current `max_allowed_packet` limit.
