Alexey Serbin created KUDU-1663:
-----------------------------------
Summary: 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
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}
