--------------------------------
Resolution: Duplicate
> Support follower linearizable read
> ----------------------------------
>
> Key: RATIS-1700
> URL: https://issues.apache.org/jira/browse/RATIS-1700
> Project: Ratis
> Issue Type: Improvement
> Affects Versions: 2.3.0
> Reporter: Song Ziyang
> Assignee: Song Ziyang
> Priority: Major
>
> The RaftPHD Thesis [section
> 6.4|https://web.stanford.edu/~ouster/cgi-bin/papers/OngaroPhD.pdf] proposes a
> approach for follower linearizable read. Despite the fact that leader has to
> make all write decesions, followers could help offload the processing of
> read-only queries. This would improve system's read throughput, and it would
> also dovert load away from leader, allowing the leader to process more
> read-write requests.
> According to experiments conducted by PingCAP, enabling follower read *double
> the read throuput of the entire system.* see
> [source|https://pingcap.com/blog/doubling-system-read-throughput-with-only-26-lines-of-code/?from=en].
> In this proposal I hope the bring the Follower Linerizable Read feture to the
> Apache Ratis Community.
