Add page rank for nodes and node labels

123joshuawu commented 3 years ago

added in_degree and out_degree to node_label
added writeNodePageRank and writeNodeLabelPageRank to PostgresKgCommandStore
added writeNodeDegreesAction and writeNodeLabelDegreesAction to PostgresKgCommandStore
call writeNodePageRank and writeNodeLabelPageRank on PostgresKgCommandStore close

other changes:

added postgres-data docker volume declaration to compose file
fixed ResultSet getArray type mismatch
fixed node sentences deserialization of empty string which was returning List("")

Remaining failing tests are for full text search

Time results from a couple quick tests:

Neo4j generally under a 0.5 seconds

Postgres fastest around 0.1 seconds but can take upwards of around 3 seconds
