Goal

Coherence heavily uses Elastic Data feature called Flash journal. In Cloud Native(CN) Elastic Charging Engine (ECE) this leads to following problem: By default, journaling-config is not configured. It means that flash-journal data is stored into /tmp (a folder inside ECS container). Also, size is not defined which can lead to unlimited growth.

In order to avoid above mentioned problem, following improvement is needed in CN ECE: extend Helm charts to enable journaling-config.flashjournal-manager.directory as a configuration variable.
Refer to the following Knowledge Article for guidelines on configuring Coherence flash journal storage and limits: How to Manage the Coherence Elastic Data use of Flash Journal File Space on Disk (Doc ID 2411335.1) - (see here )
