	"github.com/figchain/go-client/pkg/config"
	"github.com/figchain/go-client/pkg/evaluation"
)

// Define your configuration struct
type MyConfig struct {
	FeatureEnabled bool `avro:"feature_enabled"`
	MaxItems       int  `avro:"max_items"`
}

// Implement the AvroRecord interface
func (c *MyConfig) Schema() string {
	return `{

		"fields": [
			{"name": "feature_enabled", "type": "boolean"},
			{"name": "max_items", "type": "int"}
		]
	}`
}

func main() {
	// Build the client

		config.WithNamespaces("default"),
	)
	if err != nil {
		log.Fatal(err)

	// Evaluate a configuration (for traffic split support)
