Better performance? |
Early tests with a simplistic workload showed a 10% increase in throughput but increased latency (compared to blocking IO). With a limited rate 10 K msg / s, the latency is comparable to the blocking IO. The goal is to make Netty the default (and maybe only) IO layer. This way we could get rid of a significant amount of code (our NIO layer) and benefit from Netty flexibility (NIO by default, but also native IO options). |
This commit adds a Netty-based frame handler. All network IO are based on Netty when this frame handler is in use. The client library can benefit of all the flexibility and advantages of Netty: simple API, pluggable IO layer (Java NIO by default, or e.g. native Epoll on Linux). The Netty frame handler deprecates the internal one using Java NIO. The blocking IO frame handler is still the default one in 5.x. The Netty frame handler should be the only one in 6.x. Fixes #1664
