How It Affects Your App
This error indicates that the number of key parts used in a key specification exceeds the maximum limit. This can cause the application to fail to execute queries, resulting in data not being retrieved or updated. It can also lead to unexpected behavior in the application, such as incorrect results or unexpected errors. In addition, it can cause performance issues due to the extra processing required to parse the key specification.
