The endpoints need contains endpoints needed by Rasa Core.

If you're using the docker-compose version these should be prefilled for you. You'd only have to complete the analytics part if you require it.

Two endpoints have been added to the default Rasa endpoints.

rules This endpoint returns the rules in a JSON format. Rules are reloaded every minute. So you don't have to restart Core

nlu_models_info This endpoint returns an object containing the online model for each language as well as the default project language. See the Publishing models section for more details.

Analytics tracker store

Botfront comes with a custom tracker store called AnalyticsTrackerStore, which serves as a regular tracker store and provides a Chatbase integration. All you need to do is provide your chatbase API key.

The following section is particularly important if you use the EmbeddingsPolicy.

One issue we have observed with native TrackerStore implementations is a degradation in performance when the conversations gets very long. Long conversations can't be avoided on channels such as Messenger where the conversation with a user never resets. As a result, an ever longer payload gets carried around between the Core, the actions server and the database.

In most situations, only the few latest turns of the convo are needed to accurately predict the next action, so this implementation provides a mechanism to keep a limited amount of events in memory, while of course persisting everything in the database.

max_events lets you decide how many events you want to keep in memory for prediction. It defaults to 100, you might want to increase that value with the EmbeddingsPolicy. Set it to 0 if you want to keep it all in memory.

Another issue is that memory requirements grow with the number of conversations even when many sessions are inactive. To prevent that, a sweeper runs every 30 seconds to clear inactive sessions from memory. All the sessions with the latest event occuring more than tracker_persist_time seconds earlier will be swept. tracker_persist_time defaults to 3600, so every conversation inactive for more than an hour will be removed from memory. If the user comes back after an hour, the latest max_events will be fetched from the database so this mechanism is completely transparent to the user.
