MySQL 1658

This error occurs when a row is written to a table with a single-partition field, but the value of the field does not match any of the partitions.

How It Affects Your App

This error indicates that a query attempted to access a row that is not part of the same partition as the query. This can cause the application to fail to retrieve the desired data, resulting in unexpected behavior. Additionally, the application may experience performance issues due to the query attempting to access data from multiple partitions. This can lead to increased latency and decreased throughput. Finally, the application may experience data integrity issues due to the query attempting to access data from multiple partitions.
