Azure Cosmos DB vs Stellar: What are the differences?
Developers describe Azure Cosmos DB as "A fully-managed, globally distributed NoSQL database service". Azure DocumentDB is a fully managed NoSQL database service built for fast and predictable performance, high availability, elastic scaling, global distribution, and ease of development. On the other hand, Stellar is detailed as "Fast database snapshot and restore tool for development". Stellar allows you to quickly restore database when you are e.g. writing database migrations, switching branches or messing with SQL. PostgreSQL and MySQL are supported.
Azure Cosmos DB and Stellar are primarily classified as "NoSQL Database as a Service" and "Database" tools respectively.
Stellar is an open source tool with 3.58K GitHub stars and 108 GitHub forks. Here's a link to Stellar's open source repository on GitHub.
