I remember years ago watching a presentation about okio buffers using and reusing segments that contain the actual byte arrays, and avoiding a whole bunch of copying + being very performant when dealing with bigger message sizes.
At the same time i want to experiment with serialization formats that directly work with bytes as in memory, instead of doing compute to create objects then doing another compute to serialize those they simply wrap a buffer, mutate directly on that buffer and when its time to write back to the wire the buffer is ready to go... with 0 cost to serialize or deserialize a message.
This poses a challenge for applications that are expecting an object and freeling passing around or holding onto those objects for some time... meaning instead of objects i have to juggle buffers/bytearrays.
I was wondering if okio buffer could do this, essentially what i need is
be able to request a mutable/resizable Buffers but when i'm done i'd call an api and let it know im done with it...
Note its very much possible that i dont even read the whole message, but few fields at specific offests, mutate it at specific offsets... maybe i wont even write some of them to the wire (e.g. the buffer is not consumed in traditional sense but i'm done with it), it can go back into the pool to be used for something else.
