Random choice

Note

The article is being updated.

The YDB SDK uses the random_choice algorithm by default.

Below are examples of the code for forced setting of the “random choice” balancing algorithm in different YDB SDKs

Go

package main
import (
    "context"
    "os"
    "github.com/ydb-platform/ydb-go-sdk/v3"
    "github.com/ydb-platform/ydb-go-sdk/v3/balancers"
)
func main() {
    ctx, cancel := context.WithCancel(context.Background())
    defer cancel()
    db, err := ydb.Open(
        ctx,
        os.Getenv("YDB_CONNECTION_STRING"),
        ydb.WithBalancer(
            balancers.RandomChoice(),
        ),
    )
    if err != nil {
        panic(err)
    }
    defer func() {
        _ = db.Close(ctx)
    }()
}
