Couchbase is a multi-model database: you can start with simple-to-understand key-value operations and progress to SQL++ or Full-Text Search when you need those services. It’s all the same pool of data: no need to bolt on extra tools or integrations. It’s all in the box with Couchbase.
Couchbase isn’t the only NoSQL database exploring SQL. it is worth nothing that Microsoft’s CosmosDB and Amazon’s PartiQL also offer some degree of SQL compatibility (albeit not as full-featured as Couchbase’s SQL++). But the adoption of SQL++ as a standard makes for a more natural transition from legacy/relational databases.

Also, I will recommend a resource for further research on this topic: SQL++ for SQL Users, This is a book by one of the inventors of SQL, Don Chamberlain (also available for free download, courtesy of Couchbase).
NoSQL has a Difficult Learning curve
With all these ways to interact with data, it must be complicated. Mongo specifically calls out Couchbase: “this growth in functionality comes at a cost: an explosion in complexity for developers“.
However, you do not need to use all these tools right away. You can start with a familiar SQL query or a simple-to-use key-value API. Later, when your use case requires it, you can advance to more complex SQL++ for flexibility, sub-document API for performance,or a full-text search index for efficient searching.
When it comes to issues with learning NoSQL databases, they’ve been all but eliminated when it comes to Couchbase compared to others. Couchbase has constantly been working to make the developer experience smoother, such as the following:
And, I’ll again mention SQL++ because SQL is the most popular language in the world for working with data. Consider this side-by-side comparison of a SQL++ query and a Mongo query, which both return the same result:
The fact still remains that not only is the SQL example given above more concise and arguably more readable than the proprietary Mongo query language, but it’s also a standard language understood by a large percentage of developers and software professionals.
Couchbase has invested in the SQL standard for years, and in a challenging hiring market, SQL can be a skill that makes the NoSQL learning curve much less steep.
The fact remains that the core of Couchbase is a very efficient, memory-first key-value engine. This has been the case from day 1. But Couchbase has built on that core engine, and it became one of the first “multi-model” NoSQL databases.
Multi-model means that a NoSQL Database like Couchbase provides multiple ways to interact with a single pool of data:
With the above facts about Couchbase, it is highly inaccurate to say that Couchbase is only for key-value use cases.
This is a entirely a bizarre point of comparison that MongoDB calls out specifically about Couchbase.
Couchbase has a built-in Full Text Search engine powered by the popular open-source library called Bleve (which was written using Go). It’s not Lucene, but it is still a full-featured library capable of stemming, language awareness, relevancy scoring, geospatial search, fuzziness, etc.
Bleve is built right into Couchbase, and does not require any additional connectors or integrations: just create an index and start searching. The following video shows just how simple yet powerful this solution can be.
