Michael Vorburger updated FINERACT-880:
---------------------------------------
Description:
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]
