| Name | DataType | Description | Default Value |
|---|---|---|---|
| worker-id (?) | long | The unique ID for working machine | 0 |
| max-tolerate-time-difference-milliseconds (?) | long | The max tolerate time for different server’s time difference in milliseconds | 10 milliseconds |
| max-vibration-offset (?) | int | The max upper limit value of vibrate number, range [0, 4096). Notice: To use the generated value of this algorithm as sharding value, it is recommended to configure this property. The algorithm generates key mod 2^n (2^n is usually the sharding amount of tables or databases) in different milliseconds and the result is always 0 or 1. To prevent the above sharding problem, it is recommended to configure this property, its value is (2^n)-1 |
