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 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."
"I like the drive and the support of this program."
"Scalability-wise, I rate the solution a ten out of ten."
"The most valuable feature is the backup and replication service."
"Stability-wise, it is a simple solution. I rate the solution's stability 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."
"Bigtable is very user-friendly where streaming data is required."
"Latency and availability are incredible."
"Cosmos DB is a pretty stable solution. I would rate it a ten out of ten."
"It's not a specific feature that I value, but the scalability of this system is the most impressive aspect."
"One valuable feature of Microsoft Azure Cosmos DB is partitioning. Its performance is very nice."
"The most valuable feature of Microsoft Azure Cosmos DB is its ability to handle concurrency and consistency."
"It is non-SQL and helps to manage and manipulate data from the coding, rather than direct data and complex queries."
"The ability to scale automatically is very valuable. Additionally, multi-region support automatically synchronizing to a different region for multi-region applications is a cool feature. It's more of a lift with other databases to configure that extra region and set up replication, even if it's on the cloud. With Azure, it's just a button click. It's that simple."
"Azure Cosmos DB's graph queries are its most valuable feature. Although I have not yet explored vector search, it's coming to Cosmos DB, and I plan to look into it. Having data in a flat file format in a document database speeds up processes, which is the primary purpose. Additionally, Cosmos DB's use of the Mongo platform makes it intuitive and cost-effective."
 

Cons

"Improvement should be made as per customer recommended and requirements."
"The lagging problem of the product I face is an area of concern where improvements are required."
"The cost of this product is too expensive."
"It would be nice if the pay-as-you-go license were a little cheaper."
"The cost of this product is too expensive."
"I've used Bigtable for about three or four years."
"The pricing of the solution needs to be improved."
"The pricing of the solution needs to be improved."
"One area for improvement is the ease of writing SQL queries and stored procedures in Microsoft Azure Cosmos DB."
"Overall, it works very well and fits the purpose regardless of the target application. However, by default, there is a threshold to accommodate bulk or large requests."
"From a scalability perspective, the key database has to be optimized in a better way that can support auto-scaling architecture or scalability architecture."
"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."
"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."
"I think it could be better if it included more in regards to AI or if it were more exposed to AI."
"Sometimes, the solution's access request takes time, which should be improved."
"The biggest problem is the learning curve and other database services like RDS."
 

Pricing and Cost Advice

"I would like to see better pricing. It is not too expensive, but it isn't cheap either."
"The tool is not expensive."
"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."
"Cost isn’t a big hurdle for us right now. The solution is not costly."
"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."
"Azure is a pay as you go subscription."
"Cosmos should be cheaper. We actually intend to stop using it in the near future because the price is too high."
"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 Cosmos DB has improved, particularly with the new pricing for Autoscale."
