Shreya Verma shows off a new feature in SQL Server 2019 CTP 3.1:

We are expanding the graph database capabilities with several new features. In this blog we discuss one of these features that is now available for public preview in SQL Server 2019,

Shortest Path, which can be used to find a shortest path between two nodes in a graph. The shortest path function can also be used to compute a transitive closure or for arbitrary length traversals.

With CTP3.1, we are introducing a new function SHORTEST_PATH, which can be used inside MATCH to find a shortest path between any 2 nodes in a graph or to perform arbitrary length traversals. Users can specify a pattern they would like to search for in the graph using a regular expression style syntax.

I’d be interested in seeing how well it performs. But it’s good to see graph functionality fleshed out a bit more.
