3. MariaDB

MariaDB, a fork of MySQL, is known for its enhanced features, security, and performance. It is fully compatible with MySQL and is used in a variety of applications from small-scale to enterprise-level deployments. However, transitioning from MySQL to MariaDB requires careful planning to ensure compatibility and performance. MariaDB is increasingly being adopted for cloud-native applications, with ongoing developments aimed at improving scalability.

8. Elasticsearch

Elasticsearch is a distributed, RESTful search and analytics engine capable of handling large volumes of data. It is commonly used for log and event data analysis, search engines, and real-time analytics.

Elasticsearch can be resource-intensive, requiring careful management to optimize performance. With growing adoption in various industries, Elasticsearch is expected to continue evolving with better security features and machine learning integrations.

GitHub Repository: Elasticsearch GitHub

9. Neo4j

Neo4j is a graph database that excels at storing and querying highly connected data. It is particularly useful for applications in social networking, fraud detection, and recommendation systems.

Data modeling in a graph structure can be complex and requires a different approach compared to relational databases. As the importance of graph analytics grows, Neo4j is expected to become more prevalent in industries requiring complex data relationships.

10. CouchDB

CouchDB is a NoSQL database that uses JSON to store data, JavaScript for MapReduce indexes, and regular HTTP for its API. It’s well-suited for web applications with a focus on replication and synchronization.

CouchDB may not be the best choice for high-performance applications due to its eventual consistency model. Improvements in conflict resolution and synchronization are likely to enhance its usability.

GitHub Repository: CouchDB GitHub

11. Couchbase

Couchbase is a distributed NoSQL database that offers a flexible data model, strong consistency, and high availability. It is used in industries such as e-commerce, finance, and healthcare. Couchbase can be complex to deploy and manage, especially in distributed environments. It is expected to continue evolving with enhanced support for edge computing and real-time applications.
