In my experience, the main issue to be concerned about with tons of
fields is norms. You'll likely have to turn them off for most of the
fields unless you have plenty of RAM to burn. They are stored in byte
arrays of size maxdoc for each field (eg non sparse). Other than that, I
don't think there is a pronounced penalty in my experience for tons of
fields. 10,000 fields is probably more than I have ever seen though, so
do report back how it goes.

Hi,
Is there any practical limit on the number of fields that can be
maintained on an index?
My index looks something like this, 1 million documents. For each group
of 1000 documents I might have 10 indexed fields. This would mean in
total about 10000 fields. Am I going to run into any issues here?
The index in Ram based.
