Does neo4j have stored procedures? How to analyze the received sample?

Question

big data

There is a query, upon execution of which we get a list of sets of vertices (this list can be very large - a million, a billion ...)
This selection needs to be analyzed.
In this selection, it is necessary in a cycle, with each set of vertices, to carry out certain calculations, and write them to certain variables (which can be created dynamically during the cycle). In general, the usual "programming" operations can be performed in a cycle.
The result will be a set of these most calculated variables.

How can this be implemented on neo4j? Does neo4j have stored functions to do this?
Probably, it is better to do the analysis operations in another system? If so, which one?

PS. The selection is created from a not very large data set (several million vertices), but as a result of the query, a lot of data can be obtained, so tips from bigdata can also help here

Answer 1

Yes, there is .
