When a server shuts down and restarts, its
MEMORY
tables become empty. The master
replicates this effect to slaves as follows: The first time that
the master uses each MEMORY
table after
startup, it logs an event that notifies the slaves that the
table needs to be emptied by writing a
DELETE
statement for that table
to the binary log. See Section 13.8, “The MEMORY
(HEAP
) Storage Engine”,
for more information about MEMORY
tables.
