I couldn't find any possibilities to construct Source from MultiMap, why such Source is not provided in standard API? https://docs.hazelcast.org/docs/jet/3.2/manual/#overview-of-sources-and-sinks
While there's (currently, in Jet 3.2) no Source.multimap()
, Jet provides a way to create your own custom Sources and Sinks via a Builder API.
Please check the relevant documentation: https://docs.hazelcast.org/docs/jet/3.2/manual/#source-sink-builder
