If you search you will find that there are always the same 4-5 HN users who comment on pulsar/kafka topics arguing that Kafka is not a viable solution anymore. Even though almost everyone is still using Kafka
Meanwhile the Confluent Kafka conference seems to double in size year after year. And AWS chooses to offer Kafka as a service, rather than Pulsar. These "<Solution> is dead / not viable anymore!" comments are pretty rampant in the Big Data space. Some are true though but it still makes me roll my eyes.
These people seem to be invested (quite literally) in Pulsar disrupting Kafka's position in the pub/sub & event streaming space. This isn't to say Pulsar can't someday be superior, though. Time will tell. But Kafka has such a massive lead and it fits the needs for most people who need to do data integration that I don't see the need for everyone to uproot their solutions in favor of Pulsar.
