A simple and easy to use solution that can run on a two-course CPU
We collect customer's feedback, and then we present it to the clients It's very easy to set up and runs easily. It doesn't require great hardware and can run on a two-course CPU with four gigs. The hybrid algorithm needs improvement. I have been using Chroma for one year.  I had some trouble…

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.

Quotes from Members

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

Pros

"It's very easy to set up and runs easily."
"The solution's most valuable feature is its documentation, which allows new users to easily learn, deploy, and use it."
"It is, also in our experience, the best open source GIS enabled database, with good support from other open-source tools."
"It has completely met our needs. It works, and it is robust."
"I think this is the only decent solution for a relational database in web development."
"Because we use it in many information systems (Financial, Human Resources, Inventory Management) in several large companies with significant data flow, we have not had problems."
"The product's deployment is easy."
"Every feature in PG is first, present, but secondly mature and just works."
"The performance is good."
"Currently this is one of the best solutions on the market."
 

Cons

"I think Chroma doesn't have a ready-made containerized image available."
"The hybrid algorithm needs improvement."
"It would be good to have machine learning functionality in this solution, similar to Microsoft SQL Server and other solutions. Machine learning capability for a basic level or a common user would be useful. It can also have good reporting capabilities."
"In fact, this could be a risk, because heavily loaded production environments usually needs DBA monitoring and intervention."
"It needs to be able to cluster."
"It is possible that in the newer version this has been addressed, but I would like the deployment in microservices architecture could be improved."
"The only thing for PG vector is if the dimension limit could be increased."
"String manipulation functions can be improved."
"Scalability; Although PostgreSQL is known for handling very well large amounts of workload, NoSQL databases performs better when scaling."
"There is room to improve some user friendly properties such as input and output tools, some people may find interesting to implement MERGE as a SQL command."
 

Pricing and Cost Advice

"The current version is an open-source."
"The licensing model is good."
"Our company pays for it. There are free versions available, but for advanced features, you obviously have to pay."
"We do not pay for licensing."
"It is open-source. If you use it on-premise, it is free. It also has enterprise or commercial versions. If you go for the cloud version, there will be a cost, but it is lower than Oracle or Microsoft."
"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
"We are using the free version of PostgreSQL."
"Affordable solution."
"It is free. There is no license on it."
