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.

Reliable transactions and rich features have powered real time collaboration and faster development
PostgreSQL fully supports ACID transactions, including atomicity, consistency, isolation, and durability, which are some of the best features it offers in my experience. It also supports multiple index types, such as B-tree, Gin, Gist, and BRIN, and provides JSON and JSONB support, which is used to query semi-structured data. PostgreSQL uses Multi-Version Concurrency Control, which allows multiple users to read and write simultaneously. For extensibility, PostgreSQL allows extensions such as PostGIS and pg_trgm, which are truly useful. PostgreSQL improves reliability, performance, and scalability in production. Since it is ACID compliant, it ensures that database transactions are safe and consistent, preventing partial data updates, maintaining data integrity, and allowing multiple users to read or write data simultaneously using MVCC. Features such as foreign keys, constraints, and triggers impact data consistency by preventing invalid data. It supports read replicas, partitioning, and horizontal scaling for scalability. PostgreSQL has been very stable in my experience, handling concurrent requests reliably while maintaining data consistency with ACID transactions and accommodating concurrent users with strong data integrity, making it mature and widely used in production systems. Using PostgreSQL with Prisma allows faster development because schema migrations are automated and type-safe queries reduce the time I spend fixing database bugs, allowing me to focus more on building features while improving collaboration between developers due to a well-defined relational schema. Migration tools keep everyone's database schema synchronized, which allows multiple developers to work on backend features without conflicts. It has a rich feature set, supporting advanced features such as window functions, common table expressions (CTEs), and full-text search, with the flexibility of supporting both JSON and relational data, meaning it can behave as both a relational database and a document database. Extensibility allows PostgreSQL to add new capabilities while maintaining a strong ecosystem that integrates easily with modern backend stacks such as Node.js, Docker, and Prisma.

Pros

"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 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 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."
"It is very scalable and comes with a bonus: no licensing issues as you scale with your databases."
"The main value is that it is open source, which means it is free. Our organization has the initiative to go to open source to cut down on cost. Oracle costs us $6 million a year right now, which is killing us, and Postgres costs nothing. So, there is a big push to go to Postgres."
"It is easy to use."
"PostgreSQL is stable. It's available, stable, and reliable."
"Postgres has some functions called JSONB aggregators or other aggregators, which are quite useful."
"Initial setup is simple."
"The solution is quite stable."
"This is an open-source solution, operates at a high speed, and supports more than one SQL language."
 

Cons

"One area for improvement in CrateDB could be the command line interface, as sometimes it was not very easy to understand."
"CrateDB was good regarding scalability, though not excellent."
"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."
"The price could be better."
"The interface climate could be better."
"It is possible that in the newer version this has been addressed, but I would like the deployment in microservices architecture could be improved."
"I have noticed that user and access management should be improved."
"I'm not really able to customize it."
"PostgreSQL doesn't have a feature for temporal SQL, which is useful for gathering versions of data. This feature should be included in PostgreSQL. This feature is available in MariaDB, SQL Server, Oracle Database, and DB2."
"PostgreSQL uses high memory compared to its counterparts when a highly demanding load is involved, especially one that makes many concurrent connections to the database."
"The scalability is limited."
 

Pricing and Cost Advice

Information not available
"The need for our customers to pay for licences is contingent on their projects and budgets."
"We do not pay for licensing."
"It is also open-source so it is free."
"PostgreSQL is a free and open-source database."
"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
"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 open source. There is no licensing."
"The solution requires a license."
