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."
"PostgreSQL provides the perfect combination of freedom, reliability, stability, security, performance, power, and ease of use."
"PostgreSQL allows us to have a single database engine used for OLTP and OLAP workloads, for relational and non-relational data."
"It is very useful for both structured and unstructured data. You can store unstructured and structured data in PostgreSQL. It is easy to use. You can easily manage things through PostgreSQL Admin. It is cost-effective. Its on-premise version is free. It is agnostic of on-premise or cloud. You can install it on the cloud or on-premises. It is available with all clouds, and you can also install it on desktop or Windows Servers."
"It has completely met our needs. It works, and it is robust."
"I cannot stress how highly I recommend PostgreSQL to my fellow programmers."
"By implementing PostgreSQL, organizational databases get stabilized, no locking issues occur and report extraction is faster."
"This is an open-source product with advanced features that support OLTP/OLAP applications with the following benefits that helps organizations grow: No recurring licensing cost, huge cost savings forever, no vendor lock in, one-time migration cost, yearly major releases, increase in profit margins, completely open source, community-based FREE support available, and commercial support option."
"Besides the simple fact of being an open product that can be used at virtually no cost, the quality of the code base is extremely good."
 

Cons

"The hybrid algorithm needs improvement."
"I think Chroma doesn't have a ready-made containerized image available."
"It needs to be able to cluster."
"Sometimes, the views create problems. If you don't have the view, sometimes what happens is you need to have the drivers properly set up for PostgreSQL."
"They need to work towards making it work better in a cloud environment."
"As PostgreSQL is an open-source product, you do have to do a bit more configuration and management yourself."
"It was a bit complex to setup, although I think this was due to ignorance on the project."
"If it was free to use, it would be the perfect solution."
"I'd like to see the following improvements: Streaming replication (or similar) disconnected from the version, so we can use it for upgrades (i.e., a 9.3 version master and a 9.5 slave)."
"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."
 

Pricing and Cost Advice

"The current version is an open-source."
"We use the open-source version of PostgreSQL and not the enterprise edition."
"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."
"The licensing model is good."
"Affordable solution."
"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 is also open-source so it is free."
"It is free. There is no license on it."
