ScyllaDB Go Driver
This is a high-performance client-side driver for ScyllaDB written in pure Go.
Note: this driver is currently in alpha. Bug reports and pull requests are welcome!
Installation
go get github.com/scylladb/scylla-go-driver
Examples
ctx := context.Background()
cfg := scylla.DefaultSessionConfig("exampleks", "192.168.100.100")
session, err := scylla.NewSession(ctx, cfg)
if err != nil {
return err
}
defer session.Close()
requestCtx, cancel := context.WithTimeout(ctx, 10*time.Second)
defer cancel()
q, err := session.Prepare(requestCtx, "SELECT id, name FROM exampleks.names WHERE id=?")
if err != nil {
return err
}
res, err := q.BindInt64(0, 64).Exec(requestCtx)Please see the full example program for more information.
All examples are available in the examples directory
