[Numpy-discussion] Possible roadmap addendum: building better text file readers
Mon Feb 27 15:10:46 CST 2012
The architecture of this system should separate the iteration across the I/O from the transformation *on* the data. It should also allow the ability to plug-in different transformations at a low-level --- some thought should go into the API of the low-level transformation. Being able to memory-map text files would also be a bonus (but this would require some kind of index to allow seeking through the file).
I have some ideas in this direction, but don't have the time to write them up just yet.
