[GitHub] [bookkeeper] LiamClarkeNZ opened a new issue #2328: [Doc] How do I add a new bookie?
LiamClarkeNZ opened a new issue #2328:
URL: https://github.com/apache/bookkeeper/issues/2328
I am reading the documentation to advise a client on technical decisions. Scaling their system is part of that decision. The documentation neither explicitly or implicitly specifies how adding a new Bookie to a BookKeeper cluster works. Does it just work? Or do I need to take manual steps? Should I enable autorecovery?
Etc. etc.

Thanks @eolivelli - will the Autorecovery daemon redistribute ledger replicas when the cluster increases in size? Or does it maintain existing ensembles but utilise the new bookie for any new ledgers?

@eolivelli, How the cluster behave if we need to scale down? [Docs explain the way to manually decommission bookies](https://bookkeeper.apache.org/docs/latest/admin/decomission/), is there a way to auto-decommission the bookies when deployed on Kubernetes as Statefulset.

@rvashishth you can write a script to automate the process. You can check https://github.com/streamnative/charts/blob/master/scripts/pulsar/decommission_bookies.sh for example.

Ledgers will stay on the original bookies if they are available.
New ledgers will go to new bookies.
Broken ledgers will be replicated to new bookies.
You can create your own LedgerPlacementPolicy that drives the placement of data
