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

"Stability-wise, it is a simple solution. I rate the solution's stability a ten out of ten."
"The main benefit I receive from Google Cloud Bigtable is the managed service part."
"The solution is very convenient."
"Scalability-wise, I rate the solution a ten out of ten."
"This solution is much more scalable than more traditional databases - at least the ones we are aware of."
"If you have a lot of data, it's really scalable and it's competitive."
"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."
"Our customer is very satisfied with it."
"The high speed of Azure Cosmos DB compared to other competitors is remarkable."
"The best feature of Microsoft Azure Cosmos DB is API access, which makes it very easy to interact with the database without needing to write queries."
"The availability and latency of Azure Cosmos DB are excellent."
"This is a good product and I recommend it, especially in cases where people want to keep their information outside of the organization and on the cloud."
"It is a cloud-based solution that is easy to deploy, easy to access, and provides users with more features compared to other clouds like AWS and GCP."
"The solution is highly scalable."
"The solution is scalable, and we intend to increase our usage."
 

Cons

"The cost of this product is too expensive."
"The pricing of the solution needs to be improved."
"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."
"The lagging problem of the product I face is an area of concern where improvements are required."
"It would be nice if the pay-as-you-go license were a little cheaper."
"I've used Bigtable for about three or four years."
"The cost of this product is too expensive."
"Better documentation on how to integrate with other components would be helpful because I was struggling with this."
"I would like the speed of transferring data to be improved."
"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."
"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."
"In the long run, there should be an addition of more features, especially because this space is evolving quickly. It all boils down to how many more features you are adding, how many integrations you are supporting, and how many more APIs you have that are standard APIs."
"One area for improvement is the ease of writing SQL queries and stored procedures in Microsoft Azure Cosmos DB."
"The size of the continuation token in Azure Cosmos DB should be static rather than increasing with more data, as it can lead to application crashes. They should use a static key size."
"It would be ideal if we could integrate Cosmos DB with our Databricks. At this point, that's not possible."
 

Pricing and Cost Advice

"I would like to see better pricing. It is not too expensive, but it isn't cheap either."
"When we've budgeted for our resources, it's one of the more expensive ones, but it's still not very expensive per month."
"The pricing for Microsoft Azure Cosmos DB is good. Initially, it seemed like an expensive way to manage a NoSQL data store, but so many improvements that have been made to the platform have made it cost-effective."
"Microsoft Azure Cosmos DB's licensing costs are monthly."
"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 a highly cost-optimized solution when used correctly."
"It is cost-effective. They offer two pricing models. One is the serverless model and the other one is the vCore model that allows provisioning the resources as necessary. For our pilot projects, we can utilize the serverless model, monitor the usage, and adjust resources as needed."
"Cosmos should be cheaper. We actually intend to stop using it in the near future because the price is too high."
"Cosmos DB gave us three accounts for $400. We pay according to the usage."
