[zeromq-dev] what are the best practices to send complex objects?

[Andrzej Dworak]

Hi,
I did some extensive testing of serialization libraries (tested C++ and Java implementations) more or less 3 months ago. Two products that I liked the most were MessagePack and Google Protocol Buffers. For my case, where I need to have self-describing serialization, I've chosen MessagePack. The requirements were quite high as this is going to be used by one of a core systems at CERN to operate LHC and other accelerators. So far no problems with MP, it's a great product, well, the same as ZeroMQ :)
Cheers,
Andrzej

If you are **really** concerned about performance, I suggest you have your own protocol that both sides understand.
This way you send data as it is, the remote side would know how to interpret it.

I've been playing with MessagePack (http://msgpack.org/) for serialization and BLOSC (http://blosc.pytables.org/trac) for compression.  They seem to work pretty well together.  How fast is fast?  BLOSC is designed to move data around in memory faster than memcpy() is able to do it, and I haven't had any complaints about how fast MessagePack works (OTOH, I'm I/O bound, so I tend not to hit any limits).

Thanks,
