TimeUUID in future

[Malte]

Hi there,

We are using timeseries for a table and would like to set the TimeUUID column to a point of time in future. There we cannot use UUIDs.now().

Is there any way to generate a UUID where the timestamp is in future?

All the best,

Malte

Hi, 

Providing your own timestamp to generate a UUID is deliberately not something provided by the driver. 

However, there is a workaround for providing a timestamp to generate a UUID explained here : http://docs.datastax.com/en/drivers/java/3.0/com/datastax/driver/core/utils/UUIDs.html#timeBased--.

There are a few utility methods in the driver's UUIDs class to help dealing with UUIDs. There are methods like UUIDs#startOf() and UUIDs#endOf() that accept a timestamp, but please note that those are not suitable for inserting UUID data in Cassandra, they are valid only for range queries on UUID columns.

Cheers.
