BigTable Setup

Development Environment

The Cloud BigTable emulator can be used during development/test. See https://cloud.google.com/bigtable/docs/emulator for general setup information.

Process:

1. Run gcloud beta emulators bigtable start in the background
2. Run $(gcloud beta emulators bigtable env-init) to establish the BIGTABLE_EMULATOR_HOST environment variable
3. Run ./init-bigtable.sh to configure the emulator
4. Develop/test

Production Environment

Export a standard GOOGLE_APPLICATION_CREDENTIALS environment variable to your service account credentials. The project should contain a BigTable instance called gemachain-ledger that has been initialized by running the ./init-bigtable.sh script.

Depending on what operation mode is required, either the https://www.googleapis.com/auth/bigtable.data or https://www.googleapis.com/auth/bigtable.data.readonly OAuth scope will be requested using the provided credentials.
