Yes, there is also a limit. In general, you can hang up to 4096 objects f=
a group, and that includes datasets as well as other groups. There is als=
limitation on how deep can go the tree, which is 512 levels right now (it
can't go much beyond 1000 because of limits on recursive deepness in
Python). By making your tree wider and deeper, you can in fact save a rea=
*huge* number of objects on it, but be careful, because groups (datasets
also, but much less) takes memory (the metainformation), so, if the tree =
reasonably balanced, the limit is mainly imposed by the available memory =
your system, not because of PyTables limitations.
