This week I’m attending the 3-day Couchbase Connect event and will be reporting on some of the topics that I find most interesting.
The first day saw many sessions but I knew the N1QL update section would have a lot of technical innovations. N1QL is the SQL-like query language used on JSON documents stored in Couchbase. With Couchbase, you are not just using a key-value store but a full JSON document database that also exposes data through queries like a relational database (among other things).
Most of N1QL is identical to SQL, but there are nuances that add even more power than standard SQL provides — especially for JSON-specific features like sub-objects, array handling, and, now more refined logical data management.
