nodeTypeProperties

This procedure is intended to replicate what's in the core Neo4j product, but with the crucial difference that it supports flexible sampling options, and does not scan the entire database. The result is producing a table of metadata that is useful for generating "Tables 4 Labels" schema designs for RDBMSs, but in a more performant way.

relTypeProperties

public java.util.stream.Stream<Tables4LabelsProfile.RelTypePropertiesEntry> relTypeProperties(java.util.Map<java.lang.String,java.lang.Object> config)
