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

"The solution's most valuable feature is its documentation, which allows new users to easily learn, deploy, and use it."
"It's very easy to set up and runs easily."
"Postgres SQL is quite a good database."
"It's a useful solution, that can be widely used."
"PostgreSQL syntax is much clearer and consistent, and its stored procedures are powerful and fast."
"PostgreSQL is a great product, very mature and is evolving into other areas beyond SQL, in this times of connected devices and big data analytics, PostgreSQL can still be considered one of the key components and works very well with others."
"PostgreSQL is a perfect database to be used by small to mid-sized companies."
"There was an immediate return-on-investment of 100%."
"PostgreSQL is far more robust and mature than MySQL, especially when you think about keys and indexes."
"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."
 

Cons

"I think Chroma doesn't have a ready-made containerized image available."
"The hybrid algorithm needs improvement."
"They need to work towards making it work better in a cloud environment."
"Eliminate the transaction wraparound possibility. If transaction wraparound occurs it can be a major problem."
"I would like to have better support for real-time applications."
"It is rather complex to set up correctly. The configuration file is over 400 lines in length and many parameters have only vaguely defined suggestions."
"The search option is not very good."
"The price could be better."
"It could be more secure."
"A better export facility which is GUI friendly would be an improvement."
 

Pricing and Cost Advice

"The current version is an open-source."
"It is free. There is no license on it."
"It is free. In terms of operating costs, it basically needs the same platform on which Oracle runs."
"We do not pay for licensing."
"It is an open-source platform."
"This solution can offer a cheaper choice for customers since it is open-source."
"We use the open-source version of PostgreSQL and not the enterprise edition."
"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
"There is an annual license."
