| BitsAllocator |
Allocate 64 bits for the UID(long)
sign (fixed 1bit) -> deltaSecond -> workerId -> sequence(within the same second) |
| DefaultUidGenerator |
The unique id has 64bits (long), default allocated as blow:
sign: The highest bit is 0 delta seconds: The next 28 bits, represents delta seconds since a customer epoch(2016-05-20 00:00:00.000). |
