Guide - 7.10.19.0 New Cache API - Configuration and Metrics
Introduction
With release 7.10.19.0, a new Cache API is introduced, which allows fine grained configuration and invalidation. The new caches are based on Guava cache implementation.
Migration
Existing caches must not be migrated, but we recommend to use the new cache API as soon as possible. Some features are:
- Fully configurable via properties
- Allow weak references for keys and weak or soft references for values
- Definition of initial and maximum size
- Monitoring of caches (sizes, cache hit ration) via Prometheus /metrics endpoint (since version 7.10.25.0)
Attention
After introduction the promotion cache was reworked (7.10.22.0). Unfortunately, the default configuration of caches leads to an high memory usage of that cache. So we strongly recommend to configure the cache manually.
