Decisions about Azure Cosmos DB

Here are some stack decisions, common use cases and reviews by companies and developers who chose Azure Cosmos DB in their tech stack.

We are building cloud based analytical app and most of the data for UI is supplied from SQL server to Delta lake and then from Delta Lake to Azure Cosmos DB as JSON using Databricks. So that API can send it to front-end. Sometimes we get larger documents while transforming table rows into JSONs and it exceeds 2mb limit of cosmos size. What is the best solution for replacing Cosmos DB?

We have an in-house build experiment management system. We produce samples as input to the next step, which then could produce 1 sample(1-1) and many samples (1 - many). There are many steps like this. So far, we are tracking genealogy (limited tracking) in the MySQL database, which is becoming hard to trace back to the original material or sample(I can give more details if required). So, we are considering a Graph database. I am requesting advice from the experts.

  1. Is a graph database the right choice, or can we manage with RDBMS?
  2. If RDBMS, which RDMS, which feature, or which approach could make this manageable or sustainable
  3. If Graph database(Neo4j, OrientDB, Azure Cosmos DB, Amazon Neptune, ArangoDB), which one is good, and what are the best practices?

I am sorry that this might be a loaded question.

I am currently using Azure Cosmos DB for our IoT platform and am planning to switch to another #NoSQL database for cost and other related issues. I am also looking for a database that has higher capabilities towards reporting solutions through Power BI or other reporting tools.

Azure Cosmos DB Alternatives & Comparisons

What are some alternatives to Azure Cosmos DB?
Azure SQL Database
It is the intelligent, scalable, cloud database service that provides the broadest SQL Server engine compatibility and up to a 212% return on investment. It is a database service that can quickly and efficiently scale to meet demand, is automatically highly available, and supports a variety of third party software.
MongoDB Atlas
MongoDB Atlas is a global cloud database service built and run by the team behind MongoDB. Enjoy the flexibility and scalability of a document database, with the ease and automation of a fully managed service on your preferred cloud.
MongoDB stores data in JSON-like documents that can vary in structure, offering a dynamic, flexible schema. MongoDB was also designed for high availability and scalability, with built-in replication and auto-sharding.
Neo4j stores data in nodes connected by directed, typed relationships with properties on both, also known as a Property Graph. It is a high performance graph store with all the features expected of a mature and robust database, like a friendly query language and ACID transactions.
The MySQL software delivers a very fast, multi-threaded, multi-user, and robust SQL (Structured Query Language) database server. MySQL Server is intended for mission-critical, heavy-load production systems as well as for embedding into mass-deployed software.
