Thank you for reply.
I'm calling each update/delete function as a separate Deferred, no
explicit threads on those functions.
OK than, let's complicated it a bit with "dictionary of lists of
dictionaries" instead of simple dictionary and let's put it all under
reactor().
There are 2 incoming requests: one to "update aa1=aval100" and another
to "delete 'a1'":
a={
'a1':[{'aa1':'aval1'},{'bb1':'bval1'}],
'a2':[{'aa2':'aval1'},{'bb2':'bval2'}]
}
So "delete 'a1'" will exec always only after "update aa1=aval100" is done?
