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 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, 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."
"Bigtable is very user-friendly where streaming data is required."
"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."
"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 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."
"Scalability-wise, I rate the solution a ten out of ten."
"Cosmos DB is effective at handling large queries."
"The most valuable features of Microsoft Azure Cosmos DB were the general infrastructure, ease to use, and interface."
"The latency and availability of Microsoft Azure Cosmos DB are fantastic."
"The biggest benefit it offers is scalability. It's easier to work with concurrency and updating data."
"Cosmos DB is a pretty stable solution. I would rate it a ten out of ten."
"I truly recommend Cosmos DB because it is a serverless product."
"The features most valuable to us in Microsoft Azure Cosmos DB are the auto scale and change feed. These features allow us to do some operations that are not possible with SQL Server."
"Cosmos DB has helped our organization handle large amounts of data."
 

Cons

"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 pricing of the solution needs to be improved."
"The program is rather expensive - it depends on the size of your data."
"The cost of this product is too expensive."
"The cost of this product is too expensive."
"I've used Bigtable for about three or four years."
"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."
"The first one is the ability to assign role-based access control through the Azure portal for accounts to have contributor rights."
"One of our biggest pain points is the backup and restore functionality needs improvement. They've gotten a little better in this area. SQL Server's long-term retention is amazing, and you can restore data from years ago. You need to open a support Microsoft ticket to restore your Cosmos DB backup, and it comes in on a different Cosmos account. It's just kind of a headache to restore data."
"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."
"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."
"While Microsoft Azure Cosmos DB is generally easy to use, it has some limitations."
"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."
"I am disappointed with the lack of compatibility of the Microsoft Azure Cosmos DB emulator with Mac."
"Azure Cosmos DB is generally a costly resource compared to other Azure resources. It comes with a high cost."
 

Pricing and Cost Advice

"I would like to see better pricing. It is not too expensive, but it isn't cheap either."
"Pricing is mid- to high-end."
"Pricing is one of the solution's main features because it is based on usage, scales automatically, and is not too costly."
"The price of Microsoft Azure Cosmos DB could be a bit lower."
"The solution is a bit on the expensive side."
"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."
"Azure Cosmos DB is generally a costly resource compared to other Azure resources. It comes with a high cost. We have reserved one thousand RUs. Free usage is also limited."
"Cosmos DB is cost-effective when starting but requires careful management."
"Microsoft Azure Cosmos DB pricing is based on RUs. Reading 1 KB document costs one RU, whereas writing one document costs five RUs. Pricing for querying depends on the complexity of the query. If you increase the document size, it will automatically increase the RU cost."
