-------------------------------
Summary: Allow client to choose the read consistency level (was: Allow
client to choose to read consistency level)
> Allow client to choose the read consistency level
> -------------------------------------------------
>
> Key: HDDS-14509
> URL: https://issues.apache.org/jira/browse/HDDS-14509
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Ivan Andika
> Assignee: Ivan Andika
> Priority: Major
>
> Currently, if OM follower read is enabled, all OM followers will serve read
> requests even if the client does not enable the follower read.
> For read-only client, this might be unexpected since they expect the OM
> follower to throw OMNotLeaderException.
> We can support some kind of OM request metadata to indicate to the OM whether
> the client enables the follower read or not. This can be initial
> implementation of configurable client read consistency. Currently we only
> support LEADER_ONLY and LINEARIZABLE. However, in the future we can add
> things such as STALE_BOUNDED_READS.
