This is a backend service that uses dgraph as its storage, data loaded to dgraph is generated by csvload.go, the resulting rdf file is used to generate a bulk load data set by running:
`dgraph bulk -f output.rdf.gz -s schemaProperty.dql.gz`
Once bulk files are generated it's copied to alpha pods created using node-three-bulk.yaml deployment file and then
the init-container used to populate alpha container.
