Pulsar itself is solid but it’s true number of good clients is limited. Same is true for kafka the only reliable client is the java one. All other are based on librdkafka which still have many major bugs causing it to be stuck and not producing to new leader during leader changes. One benefit of pulsar is that the client library is completely stateless and much simple. It does not need to know where data is stored it’s all handled by the pulsar broker.
