It’s not exactly clear where we are in the Gartner Hype Cycle with respect to so-called “NoSQL” databases. We’ve definitely been through the Trough of Disillusionment, but are we in the Slope of Enlightenment or have graph, document, key-value and other such databases hit the mainstream (Plateau of Productivity)? My sense is that we’re at the front end of mainstream adoption given how quiet the media has gone on databases like Redis, Neo4j and MongoDB, despite their rising popularity.
In other words, non-relational databases have never been more popular, or more invisible in that popularity. Until Neo4j’s $325 million fund raise we’d all but forgotten databases at all, preferring to focus on shiny, new options (Snowflake, anyone?). But it’s precisely at this moment when databases have become uninteresting to talk about that they’re most interesting from an adoption perspective. Let’s take a look.
