Pass data structures across different versions of Julia?

General Usage
1

I have one piece of code I don’t control in Julia 0.3.12. I have another piece of code that I control that I would like to keep with roughly the latest julia. I need these pieces of code to exchange data fast. For example, I want to be able to send dictionaries, and ideally identical compound types/structs between the processes. (I can get by without the types/structs but dictionaries are important.) Performance is very important.

Does anyone have any recommendations on the best way to effectively serialize things? Would you use HDF5?

I was going to use TCPSocket communication to actually send the data. Would anyone do anything differently?

Thanks.

You should try JLD.jl. If that does not work, you’ll probably need to write a custom writer/reader. HDF5 would be fine for that. Also, write the file to a RAM-disk for performance. But honestly, it might be quickest to port the 0.3 code to 0.6.
