I think that all information stored in the datastore is necessary for Rasa to work. You can select just what you want, though.

You could use the mongoDB unwind command on the events array, and select only the events you want:

db.conversations.aggregate( [
    { $unwind : "$events"},
    { $match: { $and:
        [
            {"sender_id": "default"},
            { $or: [{ "events.event":"user"}, {"events.event":"bot"}]}
        ]}},
    { $project: { "sender_id": 1, "events.timestamp": 1, "events.event": 1, "events.text": 1}}
]).pretty()
