Configuring External Storage and Backends

PostgreSQL (Gateway Controller)

To use PostgreSQL as the storage backend for the Gateway Controller, update the config.toml:

[controller.storage]
type = "postgres"

[controller.storage.postgres]
host = "postgres.example.com"
port = 5432
database = "gateway"
user = "gateway"
password = "your-postgres-password"

For the full list of PostgreSQL configuration options, refer to the config template.

Redis (Gateway Runtime — Distributed Rate Limiting)

To enable distributed rate limiting across multiple Gateway Runtime instances, configure the rate limiting policy to use Redis as the backend in config.toml:

[policy_configurations.ratelimit_v1]
algorithm = "fixed-window"
backend = "redis"

[policy_configurations.ratelimit_v1.redis]
host = "redis.example.com"
port = 6379
password = "your-redis-password"

For the full list of Redis configuration options, refer to the Advanced Rate Limiting documentation.
