URL: https://github.com/apache/shardingsphere/issues/17055
Hello, the following is my code and result data, please look at the reason：
**Test code:**
object SnowFlakeUtils {
fun getId(workerId: String): Long {
val keyGenerator = SnowflakeKeyGenerateAlgorithm()
val properties = Properties()
properties.setProperty("worker-id", workerId)
keyGenerator.props = properties
keyGenerator.init()
return keyGenerator.generateKey().toString().toLong()
}
}
for (i in 1..100) {
println(SnowFlakeUtils.getId("01"))
}
**The resulting data is:**

Hi @carlyin0801
I noticed that your code creates instance of `SnowflakeKeyGenerateAlgorithm` every time in loop. Consider using the same instance of `SnowflakeKeyGenerateAlgorithm`.
