CKG dump import utility

[winternewt]

Aiming to address #9
Made a downloader script and docker-compose config to download and spin-up CKG dump instance in a docker-container, eliminating the pitfalls and entry-threshold all at once for better reproducibility.

Hi @winternewt,
many thanks for the PR, and looks good in principle, but I can't get the Docker to work on ARM. Seems to be a problem of this older version of Neo4j, 4.2.19, which I also can't seem to find on the Dockerhub page of Neo4j. I get no matching manifest for linux/arm64/v8 in the manifest list entries for all 4.2 and 4.3 versions. We always used 4.4-enterprise or newer in our pipelines, which solves the manifest problem, but then I get a separate error (probably a packaging difference between 4.2 and 4.4):

Is there a specific reason you want to use 4.2? And BTW, is there also a reason for using the community edition? We usually use enterprise, which is fine for open source projects.

Are there any use cases of running it in ARM?

We usually use enterprise,

Is it not overly restrictive for the users? The majority of people need help to afford enterprise licenses.

Of course, all modern Macs and many current Linux machines are on ARM. I think it will rather increase than decrease as well because of their efficiency, even in data centres.

Not at all. Neo4j enterprise is free of charge for non-profit research and open source.
