High-volume transactions have reduced failures and improve customer service efficiency
The best feature is performance, because of which I decided on PostgreSQL. I have also enabled the PG vector plugin on top of PostgreSQL. I have the opportunity to use two different features and two different flavors in a single product, which is the best thing about PostgreSQL. Initially, we had some hiccups around the performance part, but later we did indexing in PostgreSQL and now it is working very well. Even when we are doing 100,000 transactions in a day, PostgreSQL is working excellently. The interface is another best feature. If I need to do any query, I simply install the plugin on my local, which is pgAdmin. Through pgAdmin, I am able to communicate with PostgreSQL and execute all my SQL queries. I am getting a better UI with PostgreSQL as the backend, which is also one of the best options. PG vector is also very strong from PostgreSQL where I have implemented RAG and on a daily basis, I inject thousands of pages of PDF. More than 100 PDFs are coming into my system and one PDF is around 1,000 pages. We are injecting them into PostgreSQL and converting them into dimensions and inserting them into PG vector. The level of transactions we are doing on a daily basis is substantial, and we are getting very good throughput and low latency from PostgreSQL. When we were doing more than 50,000 transactions in a minute with the previous database, we were getting a lot of latency issues with threads getting blocked and abruptly closed unwantedly. After doing extensive research, we decided to move to PostgreSQL. Now, we are doing around 100,000 transactions in PostgreSQL and we are getting good throughput with no latency.

I see room for improvement in Qdrant based on what another platform called Weaviate offers. Qdrant provides an excellent vector database with a solid searching method. However, it could elevate its offering by integrating embedding features. Currently, for the workflow automation I build, I rely on other platforms for embedding, so incorporating this feature directly in Qdrant Cloud would eliminate the need to depend on external solutions. A pain point I have encountered was the inactive expiration of the cloud created for certain projects. If the cloud is not used for a week, it gets terminated, which is frustrating. I think increasing that inactivity window in the free tier would be beneficial, as I have faced limitations due to this seven-day inactivity rule, requiring me to reset up the cloud after its termination.

Quotes from Members

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

Pros

"The most valuable feature is the performance."
"PostgreSQL is for personal use, e.g. I've been using it for my applications."
"The PostgreSQL database is similar to the SQL Server but has a slightly different technology that has similar resources as well. If the customer has the confidence using SQL Server, they will be fairly comfortable using this solution."
"Open source products represent no cost to the organization and the basic features are sufficient to fulfill our needs."
"Out of all the open source database applications available, PostgreSQL is among the best DB storage engines with a single unified database server unlike MySQL which supports multiple storage engines for storing the data."
"PostgreSQL's feature set was excellent for our needs, and we didn't want an expensive (meaning hardware utilization) RDBMS."
"We use this solution for the interface between our property management system and the cloud-based system."
"The solution is stable; there are no bugs or glitches, it doesn't crash or freeze, it's reliable, and the performance is excellent."
"Qdrant has reduced our response time to less than one second for our 128 KB token sizes, and we are satisfied with that performance."
"Using Qdrant's hybrid search capability has improved my search results."
"Qdrant has positively impacted my organization by consuming much less time than building systems through coding."
 

Cons

"It needs more integration."
"In fact, this could be a risk, because heavily loaded production environments usually needs DBA monitoring and intervention."
"It could be improved by using parallelization. We want distributed computing."
"I find, sometimes, that it is too restrictive in cross-table/view constraints."
"Integration with other platforms could be improved."
"I have noticed that it consumes a lot of resources."
"The price could be better."
"I don't think PostgreSQL supports bulk databases, so it needs to have more capabilities in terms of managing the bulk data."
"A pain point I have encountered was the inactive expiration of the cloud created for certain projects; if the cloud is not used for a week, it gets terminated, which is frustrating."
"The area for improvement in Qdrant is its clustering capability. While it has clustering functionality, it is not easy to set up, and not everyone can configure the clustering, so there is room for improvement in the clustering configuration."
 

Pricing and Cost Advice

"It is an open-source platform."
"Our company pays for it. There are free versions available, but for advanced features, you obviously have to pay."
"It could be much cheaper. If you would like to build an application on Amazon today, PostgreSQL is the standard database with Redshift. If you want other databases, you can add them, but PostgreSQL is the basis of everything. It's a question of money, that's it."
"Affordable solution."
"The tool is cheaply priced compared to other RDBMS providers in the market."
"The licensing model is good."
"It is also open-source so it is free."
"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
