发帖数: 7881 | 2 yes, i know. but i still want to convert that twitter ID to a uuid.
actually, there are various version of uuid, time based, name based, random.
twitter gives u the time based unique ID, the first 53 bits or so defines
the time lapsed. But let's say we have a cassandra schema table whose
primary key is uuid (or timeuuid). how can I convert the twitter ID to that
cassandra uuid? |

ID) from it.
In theory, uniqueness is not guaranteed, but in practice, it is expected and
assumed to be so.
This is how UUID is created when you format your disk and how VMware assigns
