------------------------------------------
Summary: Include steps ID into metadata persisted to external
storages
Key: MARVIN-78
URL: https://issues.apache.org/jira/browse/MARVIN-78
Project: Apache Marvin
Issue Type: Bug
Reporter: Lucas Bonatto Miguel
Currently, Marvin already supports loading the most recent model when running
the engine local, and having local persistent configured.
This tend to be an issue on container-based platforms, given containers are
usually stateless.
Currently, when configured to use external persistence, like S3, Marvin is not
able to load the most recent model from S3 if it's being started from a
container, like Docker.
Steps to reproduce:
- Create a new engine and configure s3 as persistence
- Start your engine in a docker
- Run a request to the /pipeline endpoint
- Kill your container, and start it again
- You will see that marvin doesn't load the most recent model from s3
- You can try just calling `/predictor/reload?protocol=`, in order to have it
reloading the most recent model (as specified), but that will not work as well,
because the metadata file is not present at the local MARVIN_DATA folder
