memoize-simple.yaml

# This example demonstrates the ability to memoize a template.
# Cache can be configured in configmap. For example, if the cache
# ConfigMap looks like the following, then you should expect the node output
# retrieved from the cache to be "different world".
# Note that you also need to update `creationTimestamp` in
# `data.hello` to be within the `memoize.maxAge` if `maxAge` is specified in the workflow spec.
