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."
"This database is highly reliable and offers excellent disaster recovery."
"We deployed the Postgre database on CentOS, which is a version of Linux, and have experimented with our replication and other operations, and it works perfectly well."
"Postgres is rock solid when deployed according to best practices as documented by the PostgreSQL community. When it's installed correctly, PostgreSQL is an enterprise-grade solution."
"PostgreSQL is the only open source and multi-functional database solution out in the market today."
"Postgres SQL is quite a good database."
"Postgres is for our systems a very solid database, easy to use in development and easy also to manage in production environment, and that's valuable because in the end it cuts a lot of costs (also during the upgrading processes)."
"It's quite scalable."
"It is a good free RDBMS; it's stable, scalable and reliable."
 

Cons

"The hybrid algorithm needs improvement."
"I think Chroma doesn't have a ready-made containerized image available."
"It tends to be slower when processing a large number of records."
"Authentication config could be made easier."
"There could be a plugin to distribute the data on servers for the product."
"Postgres should focus on building a stronger knowledge base. They also need to expand their integration capabilities, so more tools and resources are available to manage it."
"I don't think PostgreSQL supports bulk databases, so it needs to have more capabilities in terms of managing the bulk data."
"Parallelization and some connection to analytics is needed."
"The only feature where I can see an area of improvement is with the partitioning."
"I rate PostgreSQL as a nine out of ten and I choose to knock it down a point only because it could use a better graphic user-interface."
 

Pricing and Cost Advice

"The current version is an open-source."
"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."
"It is free. In terms of operating costs, it basically needs the same platform on which Oracle runs."
"The community version of Postgre is basically free."
"It is open source. There is no licensing."
"The licensing model is good."
"The solution requires a license."
"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."
"Our company pays for it. There are free versions available, but for advanced features, you obviously have to pay."
