LDBC SNB Implementation for JanusGraph

This implementation assumes JanusGraph running as embedded Java application. All paths mentioned in configuration parameters and environments bellow should be provided in the same environment as Janusgraph server runs (Docker container, virtual machine, etc).

Dealing with dependencies

export CURRENT_DIR=$(pwd)
git clone git@github.com:ldbc/ldbc_snb_interactive_v1_driver.git /path/to/ldbc_snb_interactive_v1_driver
cd /path/to/ldbc_snb_interactive_v1_driver
mvn clean install -DskipTests
cd $CURRENT_DIR
mvn install:install-file \
   -Dfile=/path/to/ldbc_snb_interactive_v1_driver/target/driver-1.3.0-SNAPSHOT.jar \
   -DgroupId=org.ldbcouncil.snb \
   -DartifactId=driver \
   -Dversion=1.3.0-SNAPSHOT \
   -Dpackaging=jar \
   -DgeneratePom=true

Set environments

# path to application jar
export PATH_TO_LDBS_SNB_IMPLEMENTATION=./target/uber-janusgraph-1.0-SNAPSHOT.jar

Step-by-step Guide

Put all scripts from the scripts directory onto the same environment were Janusgraph server runs (Docker container, virtual machine, etc).

# load schema, indexes, vertices and edges
./complete-loader.sh
# set driver configuration for validation in interactive-validate.properties
# run validation
./run-validation.sh

JanusGraph Console

Used for testing:

bin/gremlin.sh
graph = JanusGraphFactory.open('conf/janusgraph-berkeleyje-test.properties')
graph = JanusGraphFactory.open('conf/janusgraph-berkeleyje.properties')

g = graph.traversal()

Validation Set

Validation Set
Data Format:	CSVComposite
Operations:	1321
SF:	0.3
Vertex Count:	~210k
Edge Count:	~1.09m
Load Time:	~2:30mins
Index Time:	~2:45mins

Passing Validation:

• Short Reads 7/7
• Complex Reads 12/14
• Updates 8/8

Missing handler implementations for 0 operation type(s)

Operation	Incorrect Result
LdbcQuery1	1
LdbcQuery14	1

Issues:

• Validation's expected answer for LdbcQuery1 is including the start person which it should not (see Complex Read 1 in specification). This could imply a problem with the Cypher query used to generate the validation set.
• My LdbcQuery12 is not ordering by personId.
• Implementation of LdbcQuery14 does not handle the case when there are multiple shortest paths.
• Problem with LdbcShortQuery7MessageReplies not returning results.
