On: Do you need Redis? PostgreSQL does queuing, lockin...

Is that relevant though? Some benchmarks on the web show Postgres outperforming Redis in reads as well as low-volume writes (less than 1k key-value pairs), and Redis only beating Postgres for high volume key-value writes.

I wonder what type of use cases have high volume writes.

Maybe queuing, locking and pub/sub ?

Usually none of them. Queuing is almost never high volume and rarely is pub sub.
