Web applications, content management systems, and read-heavy workloads.
3. MongoDB
MongoDB is a NoSQL database that provides horizontal scalability and flexibility for unstructured data. Unlike CockroachDB, which is SQL-based, MongoDB excels in handling schema-less, document-based data. It’s a great alternative for applications that require large-scale, real-time data management without the need for strong consistency.
Key Features:
- Document-based Storage: Supports flexible, schema-less data models.
- Horizontal Scaling: Shards data across multiple nodes.
- High Availability: Supports automatic failover with replica sets.
Pros:
- Great for unstructured or schema-less data.
