How It Affects Your App
The error ER_COALESCE_PARTITION_NO_PARTITION indicates that the application is attempting to coalesce a partition without specifying a partition name. This can cause the application to fail, as it is not able to properly coalesce the partition without the correct partition name. This can lead to data loss or corruption, as the application is not able to properly coalesce the partition. As a result, the application may not be able to properly store or retrieve data, leading to unexpected results or errors.
