Prominent pros & cons

PROS

Microsoft Azure Cosmos DB is highly valued for its scalability, allowing seamless adaptation to various concurrency and data update demands.

The platform offers excellent latency and high availability, providing real-time access and ensuring optimal performance for critical applications.

Users appreciate the flexible schema support, which simplifies data management and integration across different data models and use cases.

The robust security features and reliability of Microsoft Azure Cosmos DB, including geo-replication, enhance data protection and global accessibility.

Microsoft Azure Cosmos DB allows for efficient data storage and retrieval, particularly with its ability to handle large volumes of unstructured data quickly.

CONS

Query complexity in Microsoft Azure Cosmos DB can be challenging and requires improvement, particularly for non-traditional use cases and integration with MongoDB.

Documentation and support for integration with other services, such as Databricks, are insufficient, and many users report difficulty understanding the pricing model.

The pricing model of Microsoft Azure Cosmos DB is complicated and expensive compared to competitors, and auto-scaling features could offer more granular control.

The lack of seamless integration with other databases and support for cross-container joins complicates the data retrieval process.

Microsoft Azure Cosmos DB's documentation, particularly around indexing and RU consumption, is inadequate and needs enhancement to make it more cost-effective for users.

The value that it has added to my AI or search workloads is that I think it's optimized that process and made it easier; we have a lot of unstructured data coming from different dissimilar systems and different data sources, so correlating those things together and making sense of it has been very beneficial.

It performs very well, especially under high load where it automatically scales up the RUs, and the main advantage of Microsoft Azure Cosmos DB is its low latency, with response times in milliseconds, making it great for chatbots.

Microsoft Azure Cosmos DB has helped decrease my company's total cost of ownership; it's easier because we have less to maintain, we're not trying to set up multiple SQL servers with replication and everything, and centralization helps a lot.

Customer service and technical support from Microsoft have been all right. On a scale of 1 to 10, I would give them probably a six, maybe a hard seven at most.

To show this in real time, we need a live connection that automatically updates in response to new records being inserted. This automated updating feature is lacking in Microsoft Azure Cosmos DB compared to Databricks.

I think Microsoft Azure Cosmos DB can be improved by providing continuous backup for multi-region rights. I believe it's available for non-multi-region rights, but there are many features that are locked behind continuous backup that I can't use because it's not enabled yet.

A way Microsoft Azure Cosmos DB could be improved is through the introduction of an access control list on a row and on a specific field within the document, rather than relying on application-level coding to manage different access control lists.

Right now, the vectors are stored as floating-point numbers within the NoSQL document, which makes them inefficiently large. This leads to increased storage space requirements, and searching through a vast number of documents in the vector database becomes quite costly in terms of RUs. While the integration works well, the expense associated with it is relatively high. I would really like to see a reduction in costs for their vector search, as it is currently on the expensive side.

I wouldn't say we have benefited from the workload management by using it; we just sync data to it and make it available for people to retrieve.

The only problem I face is more with infrastructure as code templates that don't cover everything that can be set up or configured on the portal, requiring some manual work which is additional work for us.

Firstly, having a local development emulator or simulator for Azure Cosmos DB would be beneficial. It would be very handy to have a Docker container that developers can use locally.
