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

"I like the drive and the support of this program."
"The solution is very convenient."
"The most valuable feature is the backup and replication service."
"It's very user-friendly where streaming data is required."
"If you have a lot of data, it's really scalable and it's competitive."
"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."
"Bigtable is very user-friendly where streaming data is required."
"Stability-wise, it is a simple solution. I rate the solution's stability a ten out of ten."
"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."
"The most valuable feature of Azure Cosmos DB is its scalability. That is the biggest reason I use Azure Cosmos DB."
"Microsoft Azure Cosmos DB helped improve our organization's search result quality significantly when we started using it about eight years ago."
"Microsoft Azure Cosmos DB is very easy to use once you understand the process, and we have a very good team; because it is more costly compared to other services, the Microsoft product team takes customers very seriously and if any issue arises, they immediately join calls with customers to troubleshoot problems."
"The availability and latency of Azure Cosmos DB are excellent."
"Overall, I think Microsoft Azure Cosmos DB works fine; I don't remember any case where our developers or our clients have been disappointed with it."
"The solution is scalable, and we intend to increase our usage."
"Some of the best features of Microsoft Azure Cosmos DB are that it could scale, and we could still use SQL language."
 

Cons

"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."
"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."
"It would be nice if the pay-as-you-go license were a little cheaper."
"This product needs better security and transparency, and the price should be reduced."
"I've used Bigtable for about three or four years."
"The pricing of the solution needs to be improved."
"The cost of this product is too expensive."
"A further simple application is required for Brazil."
"The UI needs enhancement. Unlike SQL, Cosmos DB's UI is not as straightforward, making it a bit challenging to use efficiently."
"The model with autoscaling for RU is complicated to optimize RU consumption."
"I think Microsoft Azure Cosmos DB can be improved by providing continuous backup for multi-region rights. I believe it's available for non-multi-region rights, but there are many features that are locked behind continuous backup that I can't use because it's not enabled yet."
"Its stability can be further improved."
"We expect Cosmos DB to lead on that. There is potential for improved security features, which is important for data storage, especially for Dell Technologies."
"Azure Cosmos DB could be better for business intelligence and analytical queries."
"One area for improvement is the ease of writing SQL queries and stored procedures in Microsoft Azure Cosmos DB. Writing an SQL query and a stored procedure on top of that is a little challenging."
 

Pricing and Cost Advice

"I would like to see better pricing. It is not too expensive, but it isn't cheap either."
"Its price is very good for the basic stuff. When you go to a more complicated use case, especially when you need replication and availability zones, it gets a little costly."
"The cost is the biggest limitation of this solution."
"Its price is in the middle, neither too low nor too high."
"Cosmos DB gave us three accounts for $400. We pay according to the usage."
"I would rate Cosmos DB's cost at seven out of ten, with ten being the highest."
"It's expensive. I would rate it a seven out of ten for pricing."
"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."
"It is expensive. The moment you have high availability options and they are mixed with the type of multitenant architecture you use, the pricing is on the higher end."
