Types

type Config

type Config struct {
	DBHost     string // DBHost represents the database host
	DBPort     int    // DBPort is the database port
	DBName     string // DBName is the database name
	DBUser     string // DBUser is the database user used to connect
	DBPassword string // DBPassword is the database password
	DBSchema   string // DBSchema represents the database schema
}

Config defines the postgres events store configuration

type DurableStore
