Subject [jira] [Commented] (ACCUMULO-1528) Scans should deterministically return entries with identical timestamps
Date Fri, 21 Jun 2013 23:41:20 GMT


Christopher Tubbs commented on ACCUMULO-1528:

No, that should be unique, all the way to timestamp. There's no telling which sources will
be read first, and returned in a batch... and if it's the last key in a batch, the rest will
be skipped when the scan session continues. So, it's not only non-deterministic which order
they arrive (because of the multiple sources), it's also non-deterministic which ones will
arrive at all.

> Scans will return multiple versions of the same key (down to identical timestamps, but
possibly with different values), non-deterministically. A source identity (eg. filename/timestamp)
could be used to order these consistently.
