Overview

Example (DiscoverCluster)

db, err := ydb.Open(ctx, "grpc://localhost:2136/local")
if err != nil {
	fmt.Printf("failed to connect: %v", err)

	return
}

endpoints, err := db.Discovery().Discover(ctx)
if err != nil {
	fmt.Printf("discover failed: %v", err)

	return
}
fmt.Printf("%s endpoints:\n", db.Name())
for i, e := range endpoints {
	fmt.Printf("%d) %s\n", i, e.String())
}

Example (WhoAmI)

if err != nil {
	fmt.Printf("discover failed: %v", err)

	return
