MySQL Error 1848: Partition Operations Lock/Algorithm Incompatibility
Description
This error occurs when an `ALTER TABLE` statement attempts to modify a partitioned table while simultaneously specifying certain `LOCK` or `ALGORITHM` clauses. MySQL currently does not support combining these specific clauses with operations targeting partitions, leading to an operational incompatibility.
Error Message
Partition specific operations do not yet support LOCK/ALGORITHM
Known Causes
3 known causesUsing `LOCK` Clause with Partition Operations 🔒
Attempting to specify a `LOCK` clause (e.g., `LOCK=SHARED`, `LOCK=NONE`) in an `ALTER TABLE` statement that also targets partition-specific modifications.
Using `ALGORITHM` Clause with Partition Operations ⚙
Employing an `ALGORITHM` clause (e.g., `ALGORITHM=INPLACE`, `ALGORITHM=COPY`) within an `ALTER TABLE` statement when performing operations on partitions.
Combining Partition Changes with Unsupported Options 💻
Executing an `ALTER TABLE` statement that includes both partition-related modifications (e.g., `ADD PARTITION`, `REORGANIZE PARTITION`) and unsupported `LOCK` or `ALGORITHM` options simultaneously.
