    ### Connecting to Big Query

    Connecting to Big Query is not required for running the backend (if you run with UPDATE_DATA=false), but is required for things like catching up ledger data in redis.

    This project is pulling from SDF's `crypto-stellar` public data set, so no special credentials are required. However you will need a Google Cloud Platform project with a service account to be able to access Big Query.
