[erlang-questions] Reading An Mnesia Index (Not The Records It Points To)
Thu Apr 30 18:12:28 CEST 2009
I have an index on a table that represents a user taxonomy - how the
user has chosen to organise their world in the application.
It is a fairly dense index, that is for each indice there will be
between 30 and several hundred actual records.
At the moment to expose the taxonomy to the user I have to build a
query that returns the value of the index from every record, and then
de-duplicate that back down to get the index - which has been slow on
As far as I can tell there is no way through the published API to
simply 'read the index' but I am sure I could plow into the code and
'work it out' but I am wary of the old 'undocumented API' beartrap.
