Improves database performance, supports AI integration, and accelerates customer-focused innovation
Azure Database for PostgreSQL can be improved in the area of elastic capabilities. One of the things we were actively looking for is the elastic feature, which was made a GA at this Ignite event. I am really happy that finally in Azure, we have a product which we can use for elastic clusters. If you are bound with a single server, then you have a vertical limit. Now you do not have any limits. As long as your use case grows, we can grow. The only thing I would maybe be thinking about is we should also allow customers to pick different node sizes for every node inside the elastic eventually. Some nodes do not need that big capacity. So that may be a nice-to-have feature, though it is not a must-have at this point.

Data platform has delivered real-time casino gameplay insights but still needs broader expertise
The best features CrateDB offers in my experience include many functionalities that allow you to purge data, maintain data, keep the database clean and essentially updated. CrateDB also allows us to store many records, and I think the performance is very strong compared to other databases or technologies. CrateDB's performance stood out for me as it allowed me to query results in less than seconds, which was optimal and enabled real-time analytics. I found it to be a very distributed SQL engine, which was beneficial considering our specific requirements. It supports multi-model and flexible schemas for structured and semi-structured data, JSON, time series for loads, and BLOBs, along with integrated performance improvements and faster ingestion than what I recall from other databases, plus better query optimizations. CrateDB has positively impacted my organization by allowing us to store several years of gameplay from our Asian customers, which involves millions and millions of records generated every day. Positively, we did not experience significant downtimes or outages, meaning the gameplay was not affected at all during these two years.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Overall, Azure Database for PostgreSQL has been good for us."
"It is easy to use and optimize. It is very easy for us to understand how a chopped chunk can be translated into embedding."
"The benefits we have realized as a company from using Azure Database for PostgreSQL on Azure make the life of our customers and our solution easier."
"We transact 128 trillion data per month using Azure Database for PostgreSQL, which helps us to be more successful on every transaction that the customer is requesting from us."
"The most valuable features of Azure Database for PostgreSQL are its networking capabilities, which allow for integration with other Azure services."
"With PostgreSQL, the documentation is perfect, and using it on Microsoft is easy because there is documentation for Microsoft PostgreSQL, which I find easy to follow."
"The flexibility that we have with the JSONB functionality allowed us to get data into the system, build the POC, get it in front of people, and then as we find needs for things to be more normally normalized, we can go back and make those changes."
"Azure Database for PostgreSQL has influenced my application development process by enabling me to take some of what we used to do on-premises, with PostgreSQL hosted in virtual machines, and transition that process into a SaaS solution."
"CrateDB fit into my project very well as it was an excellent database that allowed me to query analyses I did not think I would be able to perform."
"CrateDB has positively impacted my organization by allowing us to store several years of gameplay from our Asian customers, which involves millions and millions of records generated every day, and we did not experience significant downtimes or outages, meaning the gameplay was not affected at all during these two years."
"CrateDB positively impacted my organization by reducing the time needed for processes, and its impressive scalability made it easy to start with one server and then horizontally scale to multiple nodes to retrieve data, which helped my company gain more customers."
 

Cons

"There is a stability issue where, if the database usage peaks quickly, it may crash and require intervention to restore functionality. It does not auto-heal or self-heal in such situations."
"We had to move to a CSP. This has been a significant challenge. We experienced trouble with our CSP and had to change CSPs because we could not get the level of support we needed from them."
"They can offer more RAG extensions. Currently, it only has the vector search. It does not presently support knowledge graph functionalities as Neo4j does. It also does not offer some tools to improve indexing the way other vector databases offer."
"Microsoft support for Azure Database for PostgreSQL rates about four out of ten based on my experience. You always get the same questions with Microsoft support, and it's not really straightforward."
"Coming from a traditional Oracle Exadata setup, all queries will run faster because Oracle has that optimization layer in between which optimizes it for you, which is why you pay a lot of money for that. When you come to Azure Database for PostgreSQL, that layer is gone."
"Azure Database for PostgreSQL can be improved in ways I'm very curious to explore with Horizon."
"I would add that from my perspective, Microsoft technical support isn't great; we have tickets sitting in the bucket."
"The critical service is the Azure OpenAI service. It would help to make it simpler and easier to integrate with that or cognitive services."
"CrateDB was good regarding scalability, though not excellent."
"CrateDB can be improved as it is not very popular, which means there are not many people dedicated or experienced with this particular technology, making it less usable or suitable for many companies."
"One area for improvement in CrateDB could be the command line interface, as sometimes it was not very easy to understand."
 

Pricing and Cost Advice

"There aren't any notable areas for improvement that I could see. PostgreSQL was self-sufficient with no need for additional database knowledge to maintain it."
"The pay-as-you-go pricing model plays a critical role in managing database-related costs and resource allocation. We build using Infrastructure as Code (IAC) and maintain a focus on FinOps to control Azure service costs. Some clients are pushy on price. It's critical to automate it, so we're just using it when appropriate and switching it off in certain scenarios."
"We do not pay for a full-year subscription because our usage is still at the beginning phase and not much. The pay-as-you-go model works well for us."
"The pricing experience is positive. Azure Database for PostgreSQL reduces the need for hardware investments, and the pay-as-you-go pricing model positively affects database-related costs by allowing us to start small and scale as needed."
