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.

The dynamic autoscale or serverless model of Microsoft Azure Cosmos DB has indeed helped reduce our costs and operational effort by allowing us to scale horizontally in a straightforward manner according to our needs.

Microsoft Azure Cosmos DB has reduced the database administration for us, reduced our operational cost, and provides an overall good return on our cloud investment.

The efficiency of search capabilities is significant, particularly when it comes to the flexibility of conducting in-depth, almost recursive searches that are both efficient and cost-effective.

The scalability and ease of use with the APIs of Microsoft Azure Cosmos DB have allowed us to meet our customers' expectations pretty easily with little barrier to entry.

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.

One thing which has troubled us is the cost model for Microsoft Azure Cosmos DB. It is comparatively very difficult to understand.

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.
