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

"The most valuable feature is the backup and replication service."
"Bigtable is 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."
"Stability-wise, it is a simple solution. I rate the solution's stability a ten out of ten."
"I like the drive and the support of this program."
"Scalability-wise, I rate the solution a ten out of ten."
"Microsoft Azure Cosmos DB helped improve our organization's search result quality significantly when we started using it about eight years ago."
"Cosmos is preferred because of its speed, robustness, and utilization."
"Microsoft Azure Cosmos DB has reduced our total cost of ownership by about half, allowing us to sell our product for about half of what we were selling it before, and Microsoft Azure Cosmos DB is probably 70% of the reason why that's true."
"The best feature is the velocity to make a query."
"Switching to the cloud significantly improved scalability, flexibility, and uptime."
"What I appreciate most are the latency and the access, which are guaranteed by the tool, which is really impressive."
"Cosmos DB is effective at handling large queries."
"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."
 

Cons

"The cost of this product is too expensive."
"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 lagging problem of the product I face is an area of concern where improvements are required."
"The pricing of the solution needs to be improved."
"This product needs better security and transparency, and the price should be reduced."
"The program is rather expensive - it depends on the size of your data."
"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."
"I would like to see Cosmos DB introduce a feature that would convert machine language to human-readable queries."
"I would like the speed of transferring data to be improved."
"We are at the beginning of production, and everything is working very well. The price can always be lower, but currently, it's not a problem."
"We would like to see advancements in AI with the ability to benchmark vector search capabilities, ensuring it answers questions accurately. During our initial implementation, we faced challenges with indexing and sorting, which are natively available in other offerings but required specific configurations in Cosmos."
"A couple features that would help me in architectural solutions would be customizable architecture or customizable documentation, which both Microsoft Azure or Microsoft Teams can provide."
"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."
"The price of Microsoft Azure Cosmos DB could be a bit lower."
"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."
 

Pricing and Cost Advice

"I would like to see better pricing. It is not too expensive, but it isn't cheap either."
"Cosmos DB is a managed offering, so its cost is understandably higher."
"Its cost is transparent. Pricing depends on the transaction and data size, but overall, it is cheaper compared to hosting it on your corporate network due to other factors like power consumption."
"Cosmos DB is expensive compared to any virtual machine based on conventional RDBMS like MySQL or PostgreSQL."
"Pricing is mid- to high-end."
"If you are a small organization or startup building from scratch without the Microsoft Startup Founder Club support, it could be expensive."
"Pricing is one of the solution's main features because it is based on usage, scales automatically, and is not too costly."
"Right now, I have opted for the student subscription plan, for which Microsoft charges me around 100 USD. The pricing of the solution depends on the solution's usage."
"Microsoft Azure Cosmos DB's licensing costs are monthly."
