[Haskell-cafe] Re: HDF5

[Joel Reymont]

And a related question... Would there be an advantage in using lazy  
byte strings or Bulat's streams library over HDF5? There's a good  
performance review [1] of PyTables (thin wrapper on top of HDF5) vs.  
SqlLite that I just read and it made me wonder.

I'm looking to model the trading process as (lazy?) stream processing  
where a trade represents an event in the input stream and trade and  
stop orders would be injected into the output stream.
