MariaDB Error 1484: Incorrect Partition Definition
Description
This error indicates that an operation, typically an `ALTER TABLE` statement, attempted to define or modify the number of partitions for a table in a way that conflicts with its existing partitioning scheme or internal metadata. It occurs when the proposed number of partitions does not match what MariaDB expects based on the table's current structure.
Error Message
Wrong number of partitions defined, mismatch with previous setting
Known Causes
3 known causesIncompatible ALTER TABLE
An `ALTER TABLE` statement attempts to modify partitions (e.g., `ADD PARTITION`, `DROP PARTITION`, `REORGANIZE PARTITION`) in a way that leads to an invalid or inconsistent total number of partitions compared to the table's current state.
Incorrect Partition Definition
When defining a new partitioning scheme or modifying an existing one, the specified number of partitions (e.g., `PARTITIONS N` or the range definitions) does not align with the partitioning method or existing data, causing a mismatch.
Metadata Inconsistency
The internal MariaDB system catalog (data dictionary) contains conflicting or corrupted information about the number of partitions for a table, leading to a mismatch during schema modification operations.
