[Pytables-users] Optimizing pytables for reading entire columns at a time

[Luke L. <dur...@gm...>]

Are there any performance issues with relatively large carrays?  For
example, say I have a carray with 300,000 float64s in it.  Is there some
threshold where I could expect performance to degrade or anything?

I think I remember seeing there was a performance limit with tables > 255
columns.  I can't find a reference to that so it's possible I made it up.
 However, I was wondering if carrays had some limitation like that.
