+### Thread Safety
+
+The driver itself isn't thread safe. You could use locks or channels to avoid crashes.
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"github.com/expectedsh/go-sonic/sonic"
+)
+
+func main() {
+	events := make(chan []string, 1)
+
+	// simulating a high incoming message load
+	tryCrash := func() {
+		for {
+			events <- []string{"some_text", "some_id"}
+		}
+	}
+
+	go tryCrash()
+	go tryCrash()
+	go tryCrash()
+	go tryCrash()
+
+	ingester, _ := sonic.NewIngester("localhost", 1491, "SecretPassword")
+
+	for {
+		msg := <-events
+		// Or use some buffering along with BulkPush
+		ingester.Push("collection", "bucket", msg[1], msg[0])
+	}
+}
+```
+
 Bulk push is faster than for loop on Push.
