When I call NewKnowledgeBaseInstance every time I call Execute, there is a lock contention issue with 100 concurrent calls
The source code is as follows：
package unique
import (
"fmt"
"sync"
"time"
)
var (
offset int64 = 0
lastMS int64 = 0
mutex sync.Mutex
)
// NewID will create a new unique ID string for this runtime.
// Uniqueness between system or apps is not necessary.
func NewID() string {
mutex.Lock()
defer mutex.Unlock()
millisUnix := time.Now().Unix()
if lastMS == millisUnix {
offset++
return fmt.Sprintf("%d-%d", lastMS, offset)
}
lastMS = millisUnix
offset = 0
return fmt.Sprintf("%d-%d", lastMS, offset)
}
Suggest using atomic variables
