If the total length of the
DELETE
statement for
related_table
is more than 1MB (the default
value of the
max_allowed_packet
system
variable), you should split it into smaller parts and execute
multiple DELETE
statements. You
probably get the fastest DELETE
by specifying only 100 to 1,000
related_column
values per statement if the
related_column
is indexed. If the
related_column
isn't indexed, the speed is
independent of the number of arguments in the
IN
clause.

Oh lord please, "deletando", "gerenciador", and some more 20 words i saw before throwing up are a complete insult to the portuguese grammar.
This isn't portuguese, this is plain, non-portuguese, out-of-the-ghetto brasilian!!!!!!
There was once a time where what they spoke in Brazil was Portuguese. Not anymore. Change the link of this doc. section to some (any) other thing please.
