Abstract:
The smallest Java object is 48 bytes, Java binding tools like JAXB create 100s of these per message, no wonder then that we need gigabytes or terabytes of RAM in our caches. Why not bind to pure binary and keep the same Java API? That’s what we did, the result is lass than 20th of the standard JAXB object size, that’s a saving of 95% with no cost to performance.
