Luk,DRPC itself is not deprecated, just the Linear DRPC builder. In fact I would argue that we should remove that deprecation. It was deprecated because."Trident subsumes the functionality provided by this class, so it's deprecated"https://github.com/apache/
storm/blob/ ffa607e2464a361a8f2fa548cc8043 f5a8818d04/storm-client/src/ jvm/org/apache/storm/drpc/ LinearDRPCTopologyBuilder. java#L53
But not everyone wants to nor can use trident for their topologies and as such it is still valid.If you want to file a JIRA at https://issues.apache.org/jira
under the STORM project to remove the deprecation and assign it to me (revans2) I would be happy to take care of that for you.Thanks,BobbyOn Thu, Mar 8, 2018 at 9:18 AM Łukasz Gebel <firstname.lastname@example.org> wrote:Luk.Best regards,I really appreciate any help in this matter, as it is hard to find examples of successful usages of Storm DRPC in the Internet.Does anyone know if you can trust it, and if it will or won't be removed in newest versions of Storm? Did you have some unexpected problems using it?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.Can anyone provide information how reliable is this functionality?Hi,DRPC functionality in Apache Storm looks deprecated, however it's still useful in some use cases.
My concerns: LinearDRPCTopologyBuilder is deprecated,
releases/current/Distributed-seems not to be updated (DRPC client init is outdated), there is no information which properties you should set in config (you have to dig in code) and so on. RPC.html
