Hello Balaji <balaji.rajagopa...@olacabs.com> Yes. The State holder 'sum' in my example is actually created outside the Mapper objects; so it stays where it is. I am creating 'var's inside the Mapper objects to _refer_ to the same object, irrespective of multiplicity of the Mappers. The _open_ function is helping to make that association. This indeed was the basis of my logic. So, we are on the same page, there.
However, my question was about order of creation of State holders through multiple Operators and accessing one such State holder from inside an Operator which did not create it. I understand from your response, that you sidestepped this difficulty by resorting to Redis. Redis has a global presence and hence, any operator from any partition can access it. My question was how did you share the Redis handle across partitions? Did you broadcast it? -- Nirmalya -- Software Technologist http://www.linkedin.com/in/nirmalyasengupta "If you have built castles in the air, your work need not be lost. That is where they should be.
