[Numpy-discussion] Pickle, pytables, and sqlite - loading and saving recarray's
Fri Jul 20 08:35:51 CDT 2007
Sounds very interesting! Would you mind sharing an example (with code if
possible) of how you organize your experimental data in pytables. I have
been thinking about how I might organize my data in pytables and would luv
to hear how an experienced user does that.
Given the speed differences it looks like pytables is going to be a better
solution for my needs.
Still curious however ... does no one on this list use (and like) sqlite?
Could anyone suggest any other list where I might find users of python and
sqlite (and numpy)?
