Hi Jason,
You can try nesting variable length arrays inside of your table (
http://www.pytables.org/docs/manual/ch04.html#VLArrayClassDescr). You might
need to refer to nested tables to get an idea of how to do this (
http://www.pytables.org/docs/manual/ch03.html#id332794). On the HDF5 level,
tables are just a convenient wrapper around variable length arrays of
structs. Since you can nest tables, you should be able to nest VLArrays
inside of tables.
Let us know if you run into specific problems.
Be Well
Anthony

Simplify data backup and recovery for your virtual environment with vRanger.
Installation's a snap, and flexible recovery options mean your data is safe,
secure and there when you need it. Data protection magic?
Nope - It's vRanger. Get your free trial download today.
