Subject [GitHub] incubator-metron issue #188: METRON-227 (Time based flushing)
Date Thu, 21 Jul 2016 13:30:23 GMT
Github user mmiklavc commented on the issue:
    It is a much simpler design and it leverages Storm's built-in mechanisms for performing
actions like DB flushes. Also, you don't have to worry about multi-threading in your bolt
if you want to flush prior to your buffer being full when you haven't received a tuple in
a while. e.g. I have 99 tuples and need 100 for a flush, but don't receive a tuple for n minutes
- without using tick tuples, you either just sit and wait, add a thread that needs to check
internally, or add another external bolt with a clock. 
    I'm not aware of any cons to using the TT approach. This is what tick tuples were built
