Any limit for session table?

[hjortsberg]

In my component I plan to store large amount data in sesion table.
There is a possibility that up to 10 000 single items is going to be stored for each user for about one day and there will be about 10 000 users...
(All the users won't be doing this every day)
Are there any limits or other problems with session table when it handles large amounts of data??
