Hi, We are evaluating 'Apache storm' for one of the business use cases. In this use case, the incoming transactions/stream should be processed by set of rules or logic. In this process, there is a need of considering the historical data (may be 2 weeks or a month old) also.
Understand that, Storm will give better performance to process the incoming transactions in real-time. What if we have to read the historical data from RDBMS and use that data in the bolts? Will this degrade the performance of whole cluster (as RDBMS systems might cause some delay due to the high load of reads from the parallelizing different bolts to achieve the better performance). Any suggestion on solving this situation? Please share.
