Apache Pulsar
ELI5 — The Vibe Check
Pulsar is like Kafka went to college and came back with a multi-tenancy degree and a tiered storage minor. It separates the serving layer from the storage layer so you can scale them independently. It's the messaging system that said 'what if we could have Kafka's power but with better architecture?'
Real Talk
A distributed messaging and streaming platform with a multi-layer architecture separating serving (brokers) from storage (BookKeeper). It natively supports multi-tenancy, geo-replication, tiered storage, and both queuing and streaming semantics in a single system.
When You'll Hear This
"Pulsar's tiered storage lets us keep years of events without paying for hot storage." / "We chose Pulsar over Kafka for its native multi-tenancy — each team gets isolated namespaces."
