MongoDB vs Couchbase
When comparing MongoDB vs Couchbase, you should know that Couchbase was designed so all users benefit from clustering and rebalance, which improves data safety. On the other hand, MongoDB’s performance suffers from master-slave replication, which can cause idle nodes and low hardware utilization. Another difference is that all MongoDB services share the same resources, making it impossible to isolate workloads.
Challenge 1:
Elastic capacity and scale-agnostic architecture
MongoDB leaves data at risk because it’s inflexible and can’t adapt to modern workloads
MongoDB
MongoDB’s performance suffers from master-slave replication, which can cause idle nodes and low hardware utilization.
All MongoDB services share the same resources, making it impossible to isolate workloads.
Single-node and sharded environments require different development patterns and changes to the way applications function. This discourages the use of sharding by putting the burden on the application and operations teams to know their data and tune it differently for different access patterns.
Couchbase
Couchbase was designed as a masterless, clustered, and replicated distributed database from day one – all nodes can read and write. All users benefit from clustering and rebalance, which improves data safety.
Multi-Dimensional Scaling (MDS) enables independent scaling and complete workload isolation.
With high performance at scale, application behavior is unchanged whether growing from a single dev node to 3 test nodes or to 20 production nodes in a cloud.
Challenge 2:
Performance at scale
MongoDB performance rapidly degrades as the cluster size or number of users increases

MongoDB
MongoDB's performance suffers from limited page cache capability, requiring third-party tools to achieve acceptable norms for an enterprise-scale database.
Another MongoDB disadvantage is that inefficient routing layers add complexity and latency to requests.
Also, rigid data and index partitioning limitations require slow cross-node scatter-gather methods for some queries. This approach slows query performance, especially on enterprise clusters.
Couchbase
Couchbase has a tightly managed and fully integrated caching layer for both data and indexes, and doesn’t need additional caching products for high performance.
Intelligent routing with direct application-to-node document lookup allows for efficient communications with single network hop access.
Global indexes allow indexes to be partitioned independently of data, minimizing latency for important queries.
Challenge 3:
Integrated enterprise functionality
MongoDB limits many features depending on deployment model or third-party requirements
MongoDB
MongoDB’s key disadvantage is that some of its most attractive capabilities are bolted on rather than tightly coupled to the core database. These bolt-ons include replication, sharding, limited full-text search, and SQL-based analytics.
Because MongoDB uses a unique proprietary query language that can be hard to learn (Figure 1), you must hire developers with specific platform experience in order to get lasting value.
Finally, sharded environments have functionality limitations. Stitch functions and mobile sync are available only through the hosted Atlas offering.
Couchbase
Couchbase has unified application and management APIs across document lookup, structured query, full-text search, analytics, and triggers. This gives developers easy access to all functionality, including security and management capabilities.
Couchbase’s query language extends ANSI SQL and leverages traditional database skills for easier adoption (Figure 1).
All functionality is available across all deployment models: on premises, containers, and cloud.
Challenge 4:
Mobile and edge computing
MongoDB Realm does not allow data storage and sync for the datacenter of your choice
Learn more about Couchbase vs. MongoDB Realm for mobile and edge computing >
MongoDB Realm
MongoDB Realm sync is cloud centric and relies on network connectivity, which presents an unpredictable point of failure.
Its reliance on the MongoDB Atlas backend-as-a-service (BaaS) platform to support mobile data sync service means that you can’t deploy the solution on premises, in private datacenters, or in distributed cloud environments.
This severely limits options for meeting high availability and responsiveness requirements, as your applications become dependent on an inherently unreliable internet connection.
Couchbase
Couchbase has a flexible platform that supports a variety of advanced topologies for complex edge-to-cloud hierarchies. These include peer-to-peer as well as multi-tier cloud-to-edge topologies.
You can deploy a robust sync solution anywhere you need it – on premises or hosted on any private or public cloud.
Couchbase is cloud native, so you can use cloud tools such as the Couchbase Autonomous Operator for Kubernetes to easily deploy and manage your servers on the cloud or at the edge.
