----------------------------------------
[~zhangduo], I prefer to recommend the raft library
https://github.com/sofastack/sofa-jraft. The benchmark of JRaft could refer to
https://www.sofastack.tech/projects/sofa-jraft/benchmark-performance/.

> Key: HBASE-24753
> URL: https://issues.apache.org/jira/browse/HBASE-24753
> Project: HBase
> Issue Type: New Feature
> Components: master
> Reporter: Duo Zhang
> Priority: Major
>
> For better availability, for moving bootstrap information from zookeeper to
> our own service so finally we could remove the dependency on zookeeper
> completely.
> This has been in my mind for a long time, and since the there is a dicussion
> in HBASE-11288 about how to storing root table, and also in HBASE-24749, we
> want to have better performance on a filesystem can not support list and
> rename well, where requires a storage engine at the bottom to store the
> storefiles information for meta table, I think it is the time to throw this
> idea out.
> The basic solution is to build a raft group to store the bootstrap
> information, for now it is cluster id(it is on the file system already?) and
> the root table. For region servers they will always go to the leader to ask
> for the information so they can always see the newest data, and for client,
> we enable 'follower read', to reduce the load of the leader(and there are
> some solutions to even let 'follower read' to always get the newest data in
> raft).
> With this solution in place, as long as root table will not be in a format of
> region(we could just use rocksdb to store it locally), the cyclic dependency
> in HBASE-24749 has also been solved, as we do not need to find a place to
> store the storefiles information for root table any more.
