Pretty uninformative post. Goes from count(*) to some uuids, but fails to see the bigger picture. Depending on the data, but assuming most data isn't big data:

Pretty uninformative post. Goes from count(*) to some uuids, but fails to see the bigger picture. Depending on the data, but assuming most data isn't big data: - Use integers internally, maybe suffixed by a shard-id to prevent collision, but keep order. - Use (random) external ids to access from the outside. Note that certain uuids will still leak some information: time between records, number of machines, etc.
