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 most valuable feature is the backup and replication service."
"This solution is much more scalable than more traditional databases - at least the ones we are aware of."
"I like the drive and the support of this program."
"The main benefit I receive from Google Cloud Bigtable is the managed service part."
"Scalability-wise, I rate the solution a ten out of ten."
"Bigtable is faster than other competitors in the market. It helps us collate all the data, and the security features are great. The latency is low, and the computation speed is fantastic. Bigtable 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."
"The most valuable features for our organization with Azure Cosmos DB are multi-master capability for applications, automatic failover ensuring high availability, scalability, support for multiple data models, and low-latency access."
"The solution is used because we get faster response times with large data sets than with SQL. It's essential for us because we have half a billion rows, and we need to return them quickly."
"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."
"It has been very efficient so far. The team has been using it for quite a while. I am new to the team, but they always talk about how efficient it is."
"The global synchronization feature of Azure Cosmos DB stands out as the most valuable for me."
"It's highly scalable and supports consistency, security, and multiple security options."
"The searching capability is exceptional. It is very simple and incomparable to competitors."
"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."
 

Cons

"Improvement should be made as per customer recommended and requirements."
"The pricing of the solution needs to be improved."
"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."
"The lagging problem of the product I face is an area of concern where improvements are required."
"This product needs better security and transparency, and the price should be reduced."
"I've used Bigtable for about three or four years."
"There's a little bit of a learning curve because I was new to Azure. But once you learn the tool, it's pretty straightforward."
"Areas of improvement for Microsoft Azure Cosmos DB include indexing. While it makes data retrieval easier, it also increases costs. If there's a better way to improve indexing at a lower cost, that would be really helpful, but that's the major point for now."
"Azure Cosmos DB is generally a costly resource compared to other Azure resources. It comes with a high cost."
"Sometimes, the solution's access request takes time, which should be improved."
"Azure Cosmos DB could be better for business intelligence and analytical queries."
"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."
"I had a challenging experience implementing the emulator with a Mac. I had to install the emulator in a Docker container because it is not natively compatible. A significant amount of time was spent researching how to enable HTTPS communication when connecting the container and the emulator."
"We encountered an issue with Cosmos DB's recently introduced hierarchical partition feature."
 

Pricing and Cost Advice

"I would like to see better pricing. It is not too expensive, but it isn't cheap either."
"The customer had a high budget, but it turned out to be a little bit cheaper than what they expected. I am not sure how much they have spent so far, but they are satisfied with the pricing."
"We are not consuming so much yet since we are at the beginning of using this solution. I would rate the pricing of Microsoft Azure Cosmos DB a six out of ten."
"Cosmos DB is a highly cost-optimized solution when used correctly."
"Cosmos should be cheaper. We actually intend to stop using it in the near future because the price is too high."
"Azure is a pay as you go subscription."
"From a startup point of view, it appears to be expensive. If I were to create my startup, it would not have the pricing appeal compared to the competition, such as Supabase. All those other databases are well-advertised by communities. I know there is a free tier with Azure Cosmos DB. It is just not well advertised."
"I would rate Cosmos DB's cost at seven out of ten, with ten being the highest."
"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."
