Using JAX-RS with Protocol Buffers for high-performance REST APIs — spullara

One of the great things about the JAX-RS specification is that it is very extensible and adding new providers for different mime-types is very easy. One of the interesting binary protocols out there is Google Protocol Buffers. They are designed for high-performance systems and drastically reduce the amount of over-the-wire data and also the amount of CPU spent serializing and deserializing that data. There are other similar frameworks out there including Fast Infoset and Thrift. Extending JAX-RS to support those protocols is nearly identical so all of the ideas I'll talk about are generally valid for those frameworks as well. The one limitation that we will table for now is that JAX-RS only works over HTTP and will not work for raw socket protocols and the high-performance aspect of protobufs is somewhat reduced by our dependency on the HTTP envelope. My assumption is that you have done your homework and know that message passing is your overriding bottleneck.
