Zookeeper has an external state - it's configuration file and it's
persistent database on disk.
If you use --zkConf then your zoo.cfg you'll have something like:
dataDir=./ZkData
and maybe
dataLogDir=
or have used --zkData
for the snapshot of the in-memory database and the transaction log.
If you're inside a container, the data areas will need to be external
(bind volumes) or the data will be lost when the container goes away.

BTW Just to be clear : RDF Delta is not part of Apache Jena.
I'll leave it to the Jena user community wants email about it here or not.

No, we don't do anything extra to preserve the data. We expected RDF Delta
would pick it up automatically. Could you clarify what you mean by
preserving? How can we apply it?
Thanks,

Did you preserve the Zookeeper database when redeploying?
That keeps the patch index. It is not rebuilt from S3.

Hi,
We are using RDF Delta with the Zookeeper/S3 integration. The issue is
after each redeploying of the docker compose image by Kubernetes all data
is gone despite the fact that the old patch files are still on S3 server
but RDF Delta does not see the old ones. Is this expected? How could we
make RDF Delta use the old files which are already in the expected place?
Thanks,
Piotr Nowara
