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.

One of the most valuable features is real-time data capture; it optimizes database performance. I think using real-time data capture reduces job running time and the amount of data sent at once with batch loads.

The system can perform faster analysis by providing it with a lot of memory. Speed is crucial for analytics. Currently, the main reason we haven't adopted Elasticsearch is that we lack the necessary expertise to manage it.

We managed to reduce the storage space needed to 10% of the original size, without affecting data integrity, and we significantly improved the performance.
