Resolution: Abandoned
> Fineract Caches & Kubernetes Deployment
> ---------------------------------------
>
> Key: FINERACT-880
> URL: https://issues.apache.org/jira/browse/FINERACT-880
> Project: Apache Fineract
> Issue Type: Improvement
> Components: Performance
> Reporter: Michael Vorburger
> Assignee: Benura Abeywardena
> Priority: Major
> Labels: kubernetes, scalability, technical
>
> The Kubernetes deployment contributed in FINERACT-783 by default creates a
> Kubernetes Deployment with a single Pod (based on Fineract's Docker Compose
> set-up).
> The goal of this issue is to investigate what is missing to make it possible
> to "scale horizontally" by increasing the number of replicas.
> For example, I believe Fineract code caches certain things? I'm not clear if
> they are enabled or disabled by default. Such caches typically do not "just
> work" if you scale the Kubernetes deployment, because they will cause "cache
> inconsistencies", unless the caches collaborate to invalidate entries when
> appropriate. This probably need some configuration. Some references:
> * Log about some EhCache configuration when Fineract starts
> *
> [cache.xml|https://github.com/apache/fineract/blob/develop/fineract-provider/src/main/resources/META-INF/spring/cache.xml]
> and
> [ehcache.xml|https://github.com/apache/fineract/blob/develop/fineract-provider/src/main/resources/META-INF/spring/ehcache.xml]
> in Fineract source code
