Hello Tidy Bot, Alexey Serbin, Mike Percy, Dan Burkert, David Ribeiro Alves, Kudu Jenkins, Andrew Wong,
I'd like you to reexamine a change. Please visit http://gerrit.cloudera.org:8080/8804 to look at the new patch set (#17). Change subject: KUDU-1704: add READ_YOUR_WRITES scan mode ...................................................................... KUDU-1704: add READ_YOUR_WRITES scan mode This patch adds a new read mode READ_YOUR_WRITES on tserver. In this mode, the server will pick a snapshot in the past, subject to the propagated timestamp bound, and perform a read. Moreover, the chosen snapshot timestamp is returned back to the client. The major difference between READ_AT_SNAPSHOT scan without a timestamp and READ_YOUR_WRITES scan is the latter will choose the newest timestamp within the staleness bound that allows execution of the reads without being blocked by the in-flight transactions if possible. READ_YOUR_WRITES mode is not repeatable. However, it allows client local read-your-writes/read-your-reads.
