After endless try/error I found the way to share volumes between
multiple docker-compose.ymls: You have to place those files in the same
folder. Also the import scripts must be adapted.
@appinteractive thanks for pointing out `split`. You just saved me some
days of work to refactor the import statements to use CSV instead of
JSON files.
@Tirokk when I enter `:schema` in Neo4J web UI, I see the following:
```
:schema
Indexes
ON :Badge(id) ONLINE
ON :Category(id) ONLINE
ON :Comment(id) ONLINE
ON :Post(id) ONLINE
ON :Tag(id) ONLINE
ON :User(id) ONLINE
No constraints
```
So I temporarily removed the unique constraints on `slug` and added
plain indices on `id` for all relevant node types. We cannot omit the
`:Label` unfortunately, neo4j does not allow this. So I had to add all
indices for all known node labels instead.
With indices the import finishes in:
```
Time elapsed: 351 seconds
```
🎉
@appinteractive when I keep the unique indices on slug, I get an error
during import that a node with label `:User` and slug `tobias` already
exists. Ie. we have unqiue constraint violations in our production data.
@mattwr18 @ulfgebhardt @ogerly I started the application on my machine
on the production data and it turns out that the index page
http://localhost:3000/ takes way to long. Visiting my profile page at
http://localhost:3000/profile/5b1693daf850c11207fa6109/robert-schafer
is fine, though. Even pagination works. When I visit a post page with
not too many comments, the application is fast enough, too:
