Subject How to wait for multiple processors' flowfile?
Date Wed, 10 May 2017 03:43:16 GMT
Hi guys, I'm currently using NiFi to do some ETL work and I need to handle
the following problem:

for example I have 3 self-defined processor A, B and C.
all of them contain logic to incrementally update a database table. the
table in C is created by table in A join table in B, so C depends on the
flowfiles from A and B.

So my question is is there a way for C to wait for both flowfiles from A
and B
to arrive and then start the work in C? Thanks.
