Re: Cannot delete rows from a NDB table

MaxNoOfTriggers specifies how many meta data objects you can have at most.
So this setting defines how many tables you can define with triggers. For
example defining an ordered index uses one trigger object, defining a
foreign key uses at least 3 trigger objects.

MaxNoOfFiredTriggers sets the number of concurrently firing triggers you
can have. So this is short term memory that you have that is used for
execution of transactions.

Your problem was that MaxNoOfFiredTriggers was too low for your environment.
Normally this is very unusual, but I presume there is something special that
you do, either large transactions or a highly concurrent environment combined
with various foreign keys.
