NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar.

Redpanda 是一个数据流处理平台。它与 Apache Kafka 的 API 兼容，能够使运行在 Kafka 生态系统中的架构得到比 Kafka 更好的简单性、性能和硬件效率。Redpanda 是由 C++ 编写的，因此不需要 JVM，也无须诸如 ZooKeeper 这样的外部依赖。它利用 Raft 协议进行数据复制，并通过了Jepsen 的测试来验证其正确性。在完成了一系列优化之后，Redpanda 还大大减少了尾部延迟，并提高了吞吐量。Redpanda 还为企业用户提供了一些高级功能，包括分层存储和对 WebAssembly (WASM) 的内联转换。
