I completely forgot about the CSI index. That's of course much easier than

AFAIK there is no sort functionality built into PyTables.
I think there are 4 ways to do it:
1.) load all 7.5 million records and sort it in memory (if it fits
into the memory)
2.) implement your own external sorting algorithm

Hi,
If I have three columns in a table and if i wish to sort based on one
field and then on the other what would be the recommended method.I
would be sorting atleast 75,00,000 records at a time.
ie I would like to use something equivalent the following sql query.
Select * from sample.table order
Thanks very much Francesc. Your solution worked great. Thanks again
for sharing Pytables with the community.

Hi all,
I am working on an energy trading system right now, and am looking at
pytables as a way to store some large multidimensional arrays for use with

The main data is stored as roughly 4,000 points * 24 hours * 365 days * 6

Let us say you have

Hi List,
I'm undergoing the last steps before declaring Blosc stable and I need your
help. If you have some minutes, I'd like you to run some tests suites on
Blosc in your machines. Please, go to:

That is fantastic news, indeed. Thanks! That would open up a lot of new

Hi Francesc,
I can confirm that it does work with an older hdf5 version. I ran the

Hi,
I can't create a table, which (I think) I could before updating my hdf5
and pytables versions (both self compiled).
The attached code is a minimal example that on my machine (Linux)
results in the error message below.
Any ideas about what is wrong?
All the best, Gabriel

Due to some problems that appeared with the LRU cache that shows in

the problems that have been reported in the Trac as well as this list.
