Data platform has delivered real-time casino gameplay insights but still needs broader expertise
The best features CrateDB offers in my experience include many functionalities that allow you to purge data, maintain data, keep the database clean and essentially updated. CrateDB also allows us to store many records, and I think the performance is very strong compared to other databases or technologies. CrateDB's performance stood out for me as it allowed me to query results in less than seconds, which was optimal and enabled real-time analytics. I found it to be a very distributed SQL engine, which was beneficial considering our specific requirements. It supports multi-model and flexible schemas for structured and semi-structured data, JSON, time series for loads, and BLOBs, along with integrated performance improvements and faster ingestion than what I recall from other databases, plus better query optimizations. CrateDB has positively impacted my organization by allowing us to store several years of gameplay from our Asian customers, which involves millions and millions of records generated every day. Positively, we did not experience significant downtimes or outages, meaning the gameplay was not affected at all during these two years.

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.

Pros

"CrateDB has positively impacted my organization by allowing us to store several years of gameplay from our Asian customers, which involves millions and millions of records generated every day, and we did not experience significant downtimes or outages, meaning the gameplay was not affected at all during these two years."
"CrateDB fit into my project very well as it was an excellent database that allowed me to query analyses I did not think I would be able to perform."
"CrateDB positively impacted my organization by reducing the time needed for processes, and its impressive scalability made it easy to start with one server and then horizontally scale to multiple nodes to retrieve data, which helped my company gain more customers."
"If you have PostgreSQL expertise you can run your business off PostgreSQL."
"I worked for years on Oracle, and I decided to move on PostgreSQL because I think it is a first class product."
"Postgres has some functions called JSONB aggregators or other aggregators, which are quite useful."
"It is easy to install and easy to manage."
"PostgreSQL is an amazing product, very stable, predictable and reliable with rich set of features."
"Every feature in PG is first, present, but secondly mature and just works."
"The built-in code procedural language is the most valuable. It has a built-in layer for code procedures. Its installation is very easy and quick, and it is free. It is also stable, and its performance is also good."
"It is very scalable and comes with a bonus: no licensing issues as you scale with your databases."
 

Cons

"One area for improvement in CrateDB could be the command line interface, as sometimes it was not very easy to understand."
"CrateDB can be improved as it is not very popular, which means there are not many people dedicated or experienced with this particular technology, making it less usable or suitable for many companies."
"CrateDB was good regarding scalability, though not excellent."
"PostgreSQL is a stable system, but from a security point of view, it still needs improvement."
"It could be improved by using parallelization. You want basically, distributed computing."
"The pricing could be better."
"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."
"I think that due to the lack of functionality for data warehousing, it is more suitable for operational information systems instead of BI systems."
"The only thing for PG vector is if the dimension limit could be increased."
"Also, it's only 7-8/10 when comparing it to an Oracle database."
"It could be more secure."
 

Pricing and Cost Advice

Information not available
"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 an open-source platform."
"There is an annual license."
"The community version of Postgre is basically free."
"It is free. In terms of operating costs, it basically needs the same platform on which Oracle runs."
"This solution can offer a cheaper choice for customers since it is open-source."
"It is free. There is no license on it."
"The tool is cheaply priced compared to other RDBMS providers in the market."
