Current Behavior or Linked Issues

#159 (closed)

Currently the service developer is expected to change JVM parameters like MinHeap and MaxHeap sizes for each service using JAVA_OPTS environment variable.

Instead of that, common default values that are found to be appropriate as part of performance improvements have been directly added to the base docker image. If a developer wishes to overwrite the values, they can always overwrite them using JAVA_OPTS environment variable.

Does this introduce a breaking change?

  • [NO]
