Summary: Sharing data between Bolts
Key: STORM-2755
URL: https://issues.apache.org/jira/browse/STORM-2755
Project: Apache Storm
Issue Type: Question
Reporter: Oussama BEN LAMINE
Hello,
i am facing a problem and your help will be really appreciated.
so, i am using storm 1.0.1, i prepared a topology that transfers data throw a
preparation bolt then to a python prediction bolt.
in prediction bolt i am collecting data in real time and creating group of data
then sending them to prediction function.
this topology works perfectly in one machine where the machine can process all
the data, but not in distributed cluster as each machine work separately and
some data needed for grouping can be processed by different machine.
Is there a way that bolts communicate with each other and so we can group data
even if they are on different machines?
can you please advice and thank you
