What do you like best about the product?

Unique and invaluable multi-model database where everything is accessed using one simple query language.
No more syncing with relational dbs when you need those capabilities.
Very friendly GUI with easy install and upgrade procedures that can be very simple to maintain. The GUI allows data exploration and analysis as well as query debugging in-place.
Very humble resource footprint, it is a 300MB C++ "rocket".
Excellent performance with many ways to improve and control it.
The Arango Team are all good people and are nice to meet and work with, they all are "clued in" and you do not get that offshore support feeling.

What do you dislike about the product?

Clustering stability, management and performance (scaling) may need some work.
Database-side triggers were promised for years but not there.
Locking mechanics may be further improved (and I see they are).
Some recent GUI changes are not always for the better.
Enterprise Support could be more responsive to medium and low priority cases (should take [much] less than a year, SLA need more enforcement)

What problems is the product solving and how is that benefiting you?

This is "The Tool" that allowed us to finally solve the Problem that Telco Industry could not solve for the 40 years of computer use -
Creating and Maintaining a Dynamic, Programmatically Accessible Model of the whole Network Topology and State as one Unified Landscape, without Boundaries and Visibility Limits,
open for traversal and analysis by all an any internal teams, for use cases of failure analysis, resource state detection, service integrinty (what-if) and change management in the Network Assurance usage patterns.
