Neo4j SDN 4 emulate sequence object(not UUID)

Question

Is it possible in Neo4j or SDN4 to create/emulate something similar to a PostgreSQL sequence database object?

I need this thread safe functionality in order to be able to ask it for next, unique Long value. I'm going to use this value as a surrogate key for my entities.

UPDATED

I don't want to go with UUID because I have to expose these IDs within my web application url parameters and in case of UUID my urls look awful. I want to go with a plain Long values for IDs like StackOverflow does, for example:

Answer 1

The most simplest way in Neo4j is to disable ids reuse and use node Graph ID like sequencer.

https://neo4j.com/docs/operations-manual/current/reference/configuration-settings/

Table A.83. dbms.ids.reuse.types.override

Description: Specified names of id types (comma separated) that should be reused. Currently only 'node' and 'relationship' types are supported.

Valid values: dbms.ids.reuse.types.override is a list separated by "," where items are one of NODE, RELATIONSHIP

Default value: [RELATIONSHIP, NODE]
