Are there recommended approach working with Database except Panache/Hibernate ?
Mostly i think because in our Kubernetes - the max resources allocated for single service instance - 2gb ram + 4vcore (2vcore, for 4 there is special agreement process). Under load i often see high memory pressure (gc count, high pauses, etc.). But handling http requests and dealing with CRUD is not a big problem. The huge difference appears during data batch upload into big-data system. The only service which was able to upload it's database faster than 300k record/s+ (peak ingestion) is using https://github.com/aaberg/sql2o + https://vertx.io/docs/vertx-pg-client/java/ . I don't remember numbers for services which use hibernate, but they mostly are very low.

A cache's primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer. Trading off capacity for speed, a cache typically stores a subset of data transiently. EVCache
