[erlang-questions] Mnesia Fragmented tables..... feature or bug?

[Eranga Udesh]

Thanks for the reply. 

However my question is when using Fragmented tables and Frag module, the
returned result is only by traversing the 1st fragment of the table and is
an empty list (if no matching data in 1st fragment), even there matching
data in other fragments.

Is it due to something I do wrong or that is how it is?

Thanks,
- Eranga

>From the man page:

For efficiency the NObjects is a recommendation only and the result
may contain anything from an empty list to all available results.
