Hello ,I developed a java project based on the storm topology that process
incoming tuples in a certain way.I tested it locally and it worked perfectly in
the context of streaming tuples of course. My topology is formed of one spout
and three bolts.In my code I used Data Structures (such as
HashMaps,linkedHashmap and TreeMap) to store some information concerning the
tuple's processing and I declared them static in the topology builder class so
they could be shared by all the bolts because they need to accessed and varied
by them frequently. The problem is that when i deployed it over a remote
cluster these static attributes weren't visible (shared ) by the different
bolts (I read about it online and I concluded because of multiple JVMs). My
question is if there is a certain concept concerning "shared memory" in Apache
Storm where we can store these DataStructures for them to be shared and
accessed by all the bolts at any given time.thanks in advance for your help.
