I love the index function and promote the internal use of PyTables at my
company. The availability of a indexed method to speed the search is the main
reason why.
We are a mixed shop using c++ to create H5 (just for the raw speed … need to
keep up with streaming data) End users start with python pyTables to consume
the data. (Often after we have created indexes from python
pytables.col.col1.createIndex())
Sometimes the users come up with something we want to do thousands of times and
performance is critical. But then we are falling back to c++ We can use our
own index method but would like to make dbl use of the PyTables index.
I know the python table.where( is implemented in C.
Is there a way to access that from c or c++? Don’t mind if I need to do work
to get the result I think in my case the work may be worth it.
