------------------------------------------
Summary: Fineract Caches & Kubernetes Deployment
Key: FINERACT-880
URL: https://issues.apache.org/jira/browse/FINERACT-880
Project: Apache Fineract
Issue Type: Improvement
Reporter: Michael Vorburger
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 they caches collaborate to invalidate entries when
appropriate, and thus 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
* [package

I personally do not know the details about caching in Fineract. We should
either fine existing create new documentation about this. It would be worth to
reach out to the mailing list to start a discussion and get input on what is
required to make this work.
