# Caracol
Caracol is a service for aggregating time series from external data systems.
## Database
### Creating the database and initial users
Create a database and a user that has permissions to access it.
The following sql is an example that creates a database and a user called caracol:
-- Create the database
CREATE DATABASE caracol;
-- Create the owner role
CREATE ROLE caracol;
GRANT caracol TO postgres;
ALTER DATABASE caracol OWNER TO caracol;
GRANT ALL PRIVILEGES ON SCHEMA public TO caracol;
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO caracol;
-- The following is run substituting the passwords
-- ALTER ROLE caracol WITH LOGIN PASSWORD '';
ALTER ROLE caracol_ro WITH LOGIN PASSWORD '';
### Creating and updating the schema
This project uses [tern](https://github.com/jackc/tern) to manage the database schema.
Install using `go install github.com/jackc/tern/v2@latest`
To update the database to the latest schema run `tern migrate` in the `migrations` directory.
Supply database details through environment variables or on the command line:
tern migrate --conn-string postgres://user:password@hostname:5432/caracol?sslmode=disable
