Yingyi Bu commented on ASTERIXDB-1289:
--------------------------------------
Yes, definitely.
Since we already have cluster-wide unique resource id for storage files, I
guess an auto-generated key in a "to-be-inserted" tuple could consist of
Resource_ID, <the number of tuples in the resource>. The tricky part is to
get the tuple count from a resource ID because we do not store that
physically...

> Key: ASTERIXDB-1289
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-1289
> Project: Apache AsterixDB
> Issue Type: Bug
> Reporter: Michael Blow
> Original Estimate: 6h
> Remaining Estimate: 6h
>
> UUIDs are generated by Asterix runtime for certain use cases; the uniqueness
> of the UUIDs relies on series of bytes obtained by SecureRandom on each NC.
> This could be improved by having the NCs obtain a unique pool from the CC to
> guarantee cluster-wide uniqueness.
