Achievement Unblocked: Switching Apache Cassandra to Netty and non-blocking I/O - A followup

In this talk we’ll cover the details of the implementation in Apache Cassandra 4.0 for migrating the internode messaging and streaming components from the current blocking IO to a netty-based, non-blocking IO solution. I’ll cover what needed to change in the internode communications protocol, how the handshake got remapped into the new handlers, how the pipelines are dynamically constructed and updated, and the actually message/streaming processing. I’ll also cover how we can easily use the TLS components in netty to make the securing communication between nodes dramatically faster. (The session will be in English)
