We've just taken a big step for the Kroxylicious project! Proposal 70 has merged — the result of a lot of hard work shaping the Routing API. There's plenty of code to follow before it's a usable thing, but this lays the foundation. github.com/kroxylicious... #ApacheKafka

We promised more details on those Kroxylicious numbers kroxylicious.io/benchmarking... Shortest possible summary: we built a second cluster because the first one was lying to us. The full story catching that lie, and how complicated reliable numbers really are: kroxylicious.io/benchmarking...
Does my proxy look big in this cluster?
Every good benchmarking story starts with a hunch. Mine was that Kroxylicious is cheap to run — I’d stake my career on it, in fact — but it turns out that “trust me, I wrote it” is not a widely accept...

Just how fast does a crocodile swim? New post: measuring the overhead Kroxylicious adds to Apache Kafka. Passthrough: below measurement noise. Record encryption: ~25% throughput hit, but Kafka never sees the plaintext. Open source benchmark harness — run it yourself. kroxylicious.io/benchmarking...

Big news: kroxylicious.io/blog/kroxyli... While we've had ideas around routing, one virtual cluster fronting multiple target clusters, for a while we have recently turned them into something tangible! Check out the blog & tell us how that fits your use cases, what things it allows you!
A proof of concept for Routing
tl;dr: We’ve built a proof-of-concept (POC) routing capability that allows Kafka clients to produce and consume records to topics in multiple clusters. In other words, clients don’t need to know where...

This #Current26 talk uses very Confluent specific tooling (unsurprisingly) but if you want encryption at rest you can use the OSS @kroxylicious.io Kafka proxy kroxylicious.io/use-cases/#e... Kroxy has a pluggable architecture so record masking and other privacy features can be added in easily
