-----------------------------
Summary: Support streaming read for replicated log
Key: MESOS-1944
URL: https://issues.apache.org/jira/browse/MESOS-1944
Project: Mesos
Issue Type: Story
Components: replicated log
Reporter: Jie Yu
Priority: Minor
It'll be great if replicated log can support streaming read so that the user
can specify a start position and get a stream object. He can then read from
that stream object. This would allow users to perform reads on a follower.
If an unlearned position is encountered, there are couple of options. One
option is to wait until it gets learned. However, it's likely that that
position never gets learned. We also don't wanna blindly do active read (full
paxos round) because it will possibly demote the leader. One solution is to
wait for the next learned event and then do active read for the positions
in-between.
