Yes, that m
I'd like to have all the attributes in memory (because I assume they
are small and I need to search them a lot) but have the data in the
tables paged in and out of memory as I need it.
Is that a realistic expectation?

I'm wondering if it might be better creating a representation of the
attributes in memory using dicts. The code I posted takes about a
second at the moment and I'll need to do lots of lookups by attributes
and I'll end up with thousands of tables.
I'll try those changes when I'm back at work

Hi
I currently have 160 or so tables with attributes on. I wish to find the
all the tables with a certain set of attributes. This code is running a
little slow:
def getTables(tsdb, attributes):
answer = []
for node in tsdb:
if isinstance(node, pytables.Leaf):
matches =
10 matches
