Component wrapping a SQL connection, for usage in org.clojure/java.jdbc.

Argument reference for SQLConnection:

• :secret-store A value that satisfies lore.api.async/IAsyncSecretStore. Typically this is another component (e.g. lore.component/SecretStore). Only used if the password is encrypted in arg-map.
• :connection-type A keyword, either :static or :rds.
• :arg-map A map of arguments.

For :static connection types, arg-map should be a java.jdbc DB spec map, but may also contain a key :encrypted-password instead of :password. If no :password is given but :encrypted-password is, it should be a base-64 encoded string, byte array, or input stream containing the encrypted password. On start, the encrypted password is decrypted via the secret-store.

For :rds connection types, the :encrypted-password key is handled as above, and the other arguments are:

• :cluster-id The name of the RDS cluster to look up (required).
• :dbname The DB name to connect to.
• :user The database user to authenticate with.
• :read-only? A boolean, if true, fetch the read-only endpoint of the cluster, if available. Otherwise fetches the main endpoint. Default true.
• aws Argument map to pass to cognitect.aws.client.api/client, to override any defaults.
• rds-client to pass an existing AWS client instance.
• expires a java.time.Duration, java.time.Period, long (milliseconds) or string (ISO duration string); how long to cache RDS results before fetching the config again. Default is to never expire.
