Fully agree that the wiki could be improved with more up-to-date documentation. Developers and reviewers have generally been diligent in ensuring that code is well documented and kept up to...

hostname is in fact triplicated in `RouterConfig`. I think `ClusterMapConfig` is the right place and all components wanting host and port should be able to source it from there.

@heipacker It is stable in the current version, have not cut a release yet but we are good to do that now. Are you looking for artifacts in Maven?

@siepkes thanks for bringing this to our attention. I assume you set this as part of `clustermap.dcs.zk.connect.strings` config? What errors did you see in the logs, could you paste them...

@zzmao is this related to this issue? If not, could you raise this as a separate issue and (describe in more details the command that you ran and so on)

@zzmao sounds good overall. Just wondering if `GetBlobResult` will need any change at all. Go ahead and put up the PR and we can discuss these there.

@rabzu @ilyai as the error message says, this happens when the router sends out request to the datanode but does not receive a response within the preconfigured expiry time. This...

All good points, @siepkes. A key-value API for Ambry is certainly useful and this is something that has come up before. Self generation of handles keeps things simple internally, particularly...

About the last part - Ambry already has the [support](https://github.com/linkedin/ambry/pull/427) for fetching bytes of a blob from a given range. #556 has been opened to add docs about it to...
