Alexey Serbin updated KUDU-1663:
--------------------------------
Status: In Review (was: In Progress)
> Clean-up in-code documentation for KuduScanner::ReadMode and
> KuduClient::GetLatestObservedTimestamp
> ---------------------------------------------------------------------------------------------------
>
> Key: KUDU-1663
> URL: https://issues.apache.org/jira/browse/KUDU-1663
> Project: Kudu
> Issue Type: Bug
> Components: api, client, documentation
> Affects Versions: 1.0.0
> Reporter: Alexey Serbin
> Assignee: Alexey Serbin
> Priority: Minor
>
> After reading the in-line doc for the subj. entities, one would expect the
> scanner from the following code to do its job on
> reading-what-you-have-written:
> {code}
> const uint64_t snapshot_timestamp = client->GetLatestObservedTimestamp();
> KuduScanner scanner(table.get());
> RETURN_NOT_OK(scanner.SetSnapshotRaw(snapshot_timestamp));
> RETURN_NOT_OK(scanner.SetReadMode(KuduScanner::READ_AT_SNAPSHOT));
> RETURN_NOT_OK(scanner.Open());
> {code}
> However, it does not work.
> To make it work, it's necessary to add extra 1 to the snapshot timestamp:
> {code}
> RETURN_NOT_OK(scanner.SetSnapshotRaw(snapshot_timestamp + 1));
> {code}
