Hi, I am using storm-0.8.2 in my system. My project, based on storm, opens connections to database/cache-server from spout/bolts. I need some of the connections to remain open till the topologies are active. However I would like to release these open connections from spout/bolt code when I kill my topology.
Could you please tell me how the resources(cache-server or database connections) in bolts/spouts can be released using storm 0.9.3 and higher versions? I am planning to upgrade storm, used in my project, to storm-0.9.4 for various reasons. If I can release resources (cache-server or database connections) from spout and bolt, it would another good reason for storm upgrade. Thanks, Richards Peter.
