Detailed Description

A row in the INSERT DELAYED queue. The client thread which runs INSERT DELAYED adds its to-be-inserted row into a queue, in the form of a delayed_row object. Later the system thread scans the queue, and actually writes the rows to the table.

Note

that custom operator new/delete are inherited from the ilink class.
