Use arangodb instead of neo4j as the graph db

[anoop2811]

Following the discussion from #194, we at Guidewire Software will look at contributing with arango as the backend db

awesome @anoop2811 ! we have a refactor about to happen to make that a lot easier!

Here is the issue and the design doc that @mihaimaruseac has put together! We anticipate the API to be solidified by end January and implement it in Feb! So that could be a good opportunity for us to have 2 implementations being worked on together!

I'd be happy to set some time up to have a chat to find out more about what you're working on!

This is indeed fascinating. Will also serve to test that the API interface is modular to support backend transparency

[anoop2811]

That would be great. Happy to discuss our plans and we are hoping GUAC can help us get there. cc: @saipraveen88

Related to issue #851 to determine which DB to support based on community input.

I've tested ArangoDB and several other databases and the result is that ArangoDB is significantly faster. Full post at https://mihai.page/testing-graph-databases/

Closing as ArangoDB has been added as a graphDB to GAUC: https://github.com/guacsec/guac/tree/main/pkg/assembler/backends/arangodb
