faucet-common-redshift

Shared connection, credentials, and connection-pool types for the faucet-stream Amazon Redshift source (faucet-source-redshift) and sink (faucet-sink-redshift) connectors.

Redshift speaks the PostgreSQL wire protocol, so both connectors connect through sqlx's Postgres driver. This crate centralises that so TLS, auth, and pooling behave identically on both sides.

Types

• RedshiftCredentials — adjacently-tagged { type, config } enum:
  • password — username/password auth (the user comes from the connection block). The only mechanism implemented in v1.
  • iam / redshift_data_api — reserved for a future release; building a client with either currently returns a typed FaucetError::Config.
• RedshiftConnection — host, port (default 5439), database, user, credentials, and a tls toggle (default true). Flattened into both end configs.

Helpers

• build_connect_options(&RedshiftConnection) — pure PgConnectOptions builder. tls: true → sslmode=require; tls: false → sslmode=prefer.
• build_pool_lazy(conn, max) — lazily-connected pool (no I/O at construction).
• build_pool(conn, max) — eagerly validated pool (fails fast on bad creds).
• resolve_password(&RedshiftCredentials) — extracts the password.

Example

host: my-cluster.abc123.us-east-1.redshift.amazonaws.com
port: 5439
database: dev
user: admin
credentials:
  type: password
  config:
    password: ${env:REDSHIFT_PASSWORD}
tls: true
