DRPC functionality in Apache Storm looks deprecated, however it's still useful in some use cases.
Can anyone provide information how reliable is this functionality?
My concerns: LinearDRPCTopologyBuilder is deprecated,
seems not to be updated (DRPC client init is outdated), there is no information which properties you should set in config (you have to dig in code) and so on.
On the other hand it is possible to use components like DRPCSpout, ReturnResult (bolt) and plug them to TopologyBuilder and their work. And these components are not deprecated.
