ReactiveMongo vs Stellar: What are the differences?

Introducing ReactiveMongo and Stellar, two technologies that offer distinct features and functionalities. Below are the key differences between these two frameworks.

1. Database Compatibility: ReactiveMongo is specifically designed for MongoDB, while Stellar is a distributed SQL database that supports various SQL databases like MySQL, PostgreSQL, and SQLite.
2. Data Model: ReactiveMongo follows the document-oriented data model, where data is stored in collections of JSON-like documents. On the other hand, Stellar utilizes a relational data model with tables, rows, and columns.
3. Concurrency Handling: ReactiveMongo provides support for reactive programming and non-blocking I/O, enabling efficient concurrency handling. In contrast, Stellar incorporates distributed processing and parallel query execution for improved scalability and performance.
4. Query Language: ReactiveMongo utilizes MongoDB's query language and aggregation framework, offering powerful querying capabilities for document-based data. Stellar, being a SQL database, supports standard SQL queries with joins, subqueries, and other relational database features.
5. Join Operations: While ReactiveMongo lacks native support for joins, Stellar allows users to perform join operations across multiple tables, enabling complex data retrieval and analysis.
6. Transaction Support: In terms of transaction management, ReactiveMongo lacks full ACID compliance but offers atomic operations at the document level. On the other hand, Stellar supports ACID transactions, ensuring data integrity and consistency across multiple operations.

In summary, ReactiveMongo is tailored for MongoDB with a focus on reactive programming, while Stellar offers distributed SQL capabilities with support for various relational databases.
