It's clearly not a full blown database product, but it's still got the core elements of a database. Your data is getting replicated to multiple instances, written to disk, and an index is created for quick lookup.
It's just the table that's getting is essentially append only (excepting the cleanup processes it supports).
My point was more about the two having separate use cases - but Kafka handles write throughput much easier compared to an RDBMS due to lack of transactions and not needing to manipulate the primary table data structures.
