> Propagate timestamps for scans
> ------------------------------
>
> Key: KUDU-1679
> URL: https://issues.apache.org/jira/browse/KUDU-1679
> Project: Kudu
> Issue Type: Sub-task
> Components: tserver
> Affects Versions: 1.0.1
> Reporter: David Alves
> Assignee: Alexey Serbin
>
> We only propagate timestamps from writes to reads, not between two reads.
> This leaves the door open to unrepeatable read anomalies:
> If T1, T2 are reads from the same client where T2 starts after the response
> from T1 is received and neither are assigned timestamps by the client. It
> might be the case where T2’s observed value actually precedes T1’s value in
> the row history if T1 and T2 are performed in different servers, as T2 can be
> assigned a timestamp that is lower than T1.
