In Chapter 5. Schema and Data Modeling first there is paragraph:

The default cardinality setting is SINGLE. Note, that property keys used on edges and properties have cardinality SINGLE. Attaching multiple values for a single key on an edge or property is not supported.

and then example:

mgmt = graph.openManagement()
follow = mgmt.makeEdgeLabel('follow').multiplicity(MULTI).make()

CSV files produced in different locales have different default separators, a comma-separated file (",") is but one type of CSV.

In Sweden we usually use a semicolon (";") as separator and many CSV files use a tab as separator ("\t"). Importing CSVs requires reformatting them before import, and causes inoperability issues and f

In many places in Gaffer, correct logging string formatting is used:

apoc.array.int()

How this feature can improve the project?

By default, it is created as a string. Some customers have asked for the ability to hint at the data type.

This enable more portability on Linux platform.

If you do object.association.distinct.other_association, the distinct goes away.

This is probably good for the simple implementation, but we could have a WITH DISTINCT automatically go in there on the second association
