Consistent performance and seamless cloud integration enhance analytics capabilities while reducing management complexity
One point for improvement in Google Cloud Bigtable is that people have confusion in mapping. There are many similar products available, and Google has managed services for similar products as well. It would be easier if the journey of knowing when to use Google Cloud Bigtable versus other Cloud SQL and alternates such as Cloud Spanner is made clearer for users. Regarding additional functionality for Google Cloud Bigtable, I am uncertain if LLMs can be integrated or if Google Cloud Bigtable can act as a vector store for LLM-specific use cases where we are interacting or using generative AI capabilities.

Provides super sharp latency, excellent availability, and the ability to effectively manage costs across different tenants
For integrating Microsoft Azure Cosmos DB with other Azure products or other products, there are a couple of challenges with the current system. 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. The areas for improvement in Microsoft Azure Cosmos DB are vector pricing and vector indexing patterns, which are unintuitive and not well described. I would also like to see the parameters of Fleet Spaces made more powerful, as currently, it's somewhat lightweight. I believe they've made those changes intentionally to better understand the cost model. However, we would like to take a more aggressive approach in using it. One of the most frustrating aspects of Microsoft Azure Cosmos DB right now is that you can only store one vector per document. Additionally, you must specify the configuration of that vector when you create an instance of Microsoft Azure Cosmos DB. Once the database is set up, you can't change the vector configuration, which is incredibly limiting for experimentation. You want the ability to try different settings and see how they perform, as there are numerous use cases for storing more than one vector in a document. While interoperability within the vector database is acceptable—for example, I can search for vectors—I still desire a richer set of configuration options.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It's very user-friendly where streaming data is required."
"The main benefit I receive from Google Cloud Bigtable is the managed service part."
"Bigtable is faster than other competitors in the market, it helps us collate all the data, the security features are great, the latency is low, the computation speed is fantastic, and it is also a managed service, so you don't have to worry about anything aside from analyzing the data ingested."
"The main benefit I receive from Google Cloud Bigtable is the managed service part."
"I like the drive and the support of this program."
"The solution is very stable; we've never experienced bugs or glitches, we haven't had crashes, and it works well and as expected 100% of the time."
"Scalability-wise, I rate the solution a ten out of ten."
"Stability-wise, it is a simple solution. I rate the solution's stability a ten out of ten."
"We love the ability to land data with Cosmos DB easily. Cosmos is native to Azure, so everything works seamlessly with it. You need good data to have good AI, and Cosmos makes it easy to land the data."
"The graphical representation of data is the most valuable feature of the solution."
"The feature I have found most valuable in Microsoft Azure Cosmos DB is its scalability and speed."
"The autoscale feature is the most useful for us."
"Microsoft Azure Cosmos DB is very fast. Data retrieval and data storage are very quick."
"The ability to scale automatically is very valuable."
"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."
"Microsoft Azure Cosmos DB has helped to improve efficiency, providing good response times and allowing the storage of AI process results, which is crucial for feedback loops."
 

Cons

"When it comes to complex queries, a user can't get any help from a drop-down box and pick columns. It would be great if some improvements could be made in the aforementioned area concerning the solution."
"The cost of this product is too expensive."
"I've used Bigtable for about three or four years."
"This product needs better security and transparency, and the price should be reduced."
"It would be nice if the pay-as-you-go license were a little cheaper."
"The program is rather expensive - it depends on the size of your data."
"Improvement should be made as per customer recommended and requirements."
"The pricing of the solution needs to be improved."
"I would give a low rating to Microsoft support, as whenever I talked to them, I never got a solution. I had to guide them."
"In Microsoft manufacturing, managers really need to know about the product."
"The topic of RU consumption needs better documentation. Now that Microsoft has partnered with different LLM organizations, such as OpenAI, a bot could guide us through different metrics present in Microsoft Azure Cosmos DB."
"Better documentation on how to integrate with other components would be helpful because I was struggling with this."
"It would be nice to have more options to ingest the data, for example, more file options or more search options."
"Because there is no local way of doing things, Azure Cosmos DB will always be considered expensive."
"There were instances where the DB was not responding, and we lost some part of our business due to that."
"We had to go to forums to check if it was failing for everyone else. It was surprising that a large organization like Microsoft doesn't provide an official statement about the maintenance or issues that could impact our overall usage."
 

Pricing and Cost Advice

"I would like to see better pricing. It is not too expensive, but it isn't cheap either."
"Our experience with the pricing and setup cost is that it aligns with what we expect based on the pricing we see. However, I would absolutely like it to be less if possible."
"The solution is very expensive."
"Most customers like the flexibility of the pricing model, and it has not been an issue. They can start small, and the cost grows with adoption, allowing efficient management of the budget. Its pricing model has not been a concern at all for any of our customers. They understand it. It is simple enough to understand. Oftentimes, it is hard to forecast the RUs, but, in general, it has been fine."
"This cost model is beneficial because it allows for cost control by limiting resource units (RUs), which is ideal. However, for our needs, we can't engage with their minimum pricing, which ranges from 100 to 1,000 RUs. At the bare minimum, we need to use 4,000 RUs for a customer. I would like to find a way to gain some advantages from the lowest tier, particularly the ability to scale down if necessary. It would be helpful to have more flexibility in cost management at the lower end."
"I would rate Cosmos DB's cost at seven out of ten, with ten being the highest."
"Everything could always be cheaper. I like that Cosmos DB allows us to auto-scale instead of pre-provisioning a certain capacity. It automatically scales to the demand, so we only pay for what we consume."
"Microsoft Azure Cosmos DB is moderately priced, where it is neither expensive nor cheap."
"The pricing model of Microsoft Azure Cosmos DB is a bit complex."
