Not able to benchmark Dgraph with Neo4j

[sairam]

I am following this(Neo4j vs Dgraph - The numbers speak for themselves - Dgraph Blog) blog to benchmark Dgraph with Neo4j.

As mentioned I am trying to load equivalent data to Neo4j as well as Dgraph.(From here: benchmarks/data/neo4j at master · dgraph-io/benchmarks · GitHub)

I was able to load CSV data to Neo4j but I have some issue with Dgraph data and schema.

I tried this command to load data to Dgraph.(As mentioned in the blog)

dgraph live -f ./output.rdf -s ./goldendata.schema -a localhost:9080

Output:

The process is still running for more than an hour and ultimately I had to quit it. Any solutions???

[MichelDiz]

Hum, this is 3y old code. Hard to tell.

@pawan would you mind to check it?

[sairam]

Any update on this topic??

[pawan (Pawan Rawal)]

Hey @sairam

I am not sure where you got the output.rdf.gz from. Could you try loading the neo.rdf.gz instead?

Also please use the following schema for loading.

type.object.name: string @index(term) @lang .
film.film.initial_release_date: datetime @index(year) .

The query_test.go should also be modified a bit as things have changed with Dgraph and we don’t support querying directly by an xid anymore. We don’t have the bandwidth of working on this right now but can do this at a later point.
