We’re planning to use looker for our Rasa analytics and looker will source data from Google BigQuery.
Our Rasa system is being built currently and will be using Postgres as the data warehouse (the postgres is in Google Cloud’s Cloud SQL). Do we need to begin syncing the data (Postgres>BigQuery) as soon as the chatbot goes live or can we build that later and just backfill the data from postgres? We don’t want to lose any data because of Postgres upserts or disposition rules or anything like that. Basically - how long will the data stay in postgres?
