What changed
Message.isReplicated()andMessage.getReplicatedFrom()from the Node.js binding.Why
Consumers need access to Pulsar replication-origin metadata to distinguish locally produced messages from messages geo-replicated from another cluster. This implements #480 on top of the C++ client API added in apache/pulsar-client-cpp#583.
isReplicated()is derived from whethergetReplicatedFrom()returns a non-empty cluster name.Fixes #480
Validation
npm run type-checknpx clang-format-lint src/Message.cc src/Message.hnpx node-pre-gyp configure buildnode -e "const Pulsar=require('./'); console.log(typeof Pulsar.Message.prototype.isReplicated, typeof Pulsar.Message.prototype.getReplicatedFrom)"npx eslint tests/end_to_end.test.js(passes with existing warnings)
