[Pytables-users] append to multiple tables

[Edward V. <edw...@gm...>]

I have a dataset that I want to split between two tables. But, when I
iterate over the data and append to both tables, I get a warning:

/usr/local/lib/python2.7/site-packages/tables/table.py:2967:
PerformanceWarning: table ``/cv2`` is being preempted from alive nodes
without its buffers being flushed or with some index being dirty.  This may
lead to very ineficient use of resources and even to fatal errors in
certain situations.  Please do a call to the .flush() or .reindex_dirty()
methods on this table before start using other nodes.

However, if I flush after every append, I get awful performance.
Is there a correct way to append to two tables without doing a flush?
Note, I don't have any indices defined, so it seems reindex_dirty() doesn't
apply.

Thanks,
Ed
