- Praise: Postgres is a robust choice, but Redis shines for fast, non-critical storage — it's like having a reliable backup plan that doesn't bog down your main database.
- Praise: Redis is incredibly easy to add to your stack, offering unmatched speed and stability for caching without the headaches of managing a more complex system.
- Praise: Using Postgres for everything seems limiting; embracing specialized tools like Redis can lead to better performance and less operational stress.
- Concern: The push to use Postgres for everything feels like a one-size-fits-all approach that ignores the nuances of different use cases and the need for specialized solutions.
- Concern: Articles promoting Postgres as the ultimate solution risk creating an echo chamber, potentially leading to poor decisions when the realities of system demands hit.
- Concern: Reliance on Postgres extensions can lead to unnecessary complexity, making it harder to maintain a clean and efficient architecture.
