MariaDB Error 1616: Unsupported DELAYED Insert
Description
This error occurs when an `INSERT DELAYED` statement is attempted on a table that does not support the `DELAYED` clause. This option is primarily designed for MyISAM tables to queue inserts during high concurrency, but is not implemented by other common storage engines like InnoDB or NDB.
Error Message
DELAYED option not supported for table '%s'
Known Causes
3 known causesUnsupported Storage Engine
The target table uses a storage engine (e.g., InnoDB, NDB Cluster, CSV) that does not support the `DELAYED` insert functionality.
Temporary Table Usage
The `INSERT DELAYED` statement is being executed against a temporary table, which inherently does not support this option.
Partitioned Table Target
The table specified in the `INSERT DELAYED` statement is a partitioned table, a configuration that does not allow delayed inserts.
