| Subject | Can I make a bolt to do a batch job? |
| Date | Fri, 11 Jul 2014 08:05:38 GMT |
Hi all, Assume that there are one spout and one bolt. and spout emits a single log, and bolt stores it into DB for example. and they are connected using shuffle grouping. It comes to my mind that if a bolt can wait for 10 tuples to come from spout, and request batch insert to DB, it might be beneficial performancewise. Is there any way to make a bolt gather tuples until certain size and do it's job? | |
