Full planet build wof data

[tk2232]

I have some questions that are difficult to understand as a beginner.

I want to do a full planet build.

In the helm chart only the data for portland metro are downloaded.
If I want other data I have to do a separate build and
adjust the index in the config. Up to here everything is understandable.

Questions

1. Do the wof data have to be present for pip or does pip also access elasticsearch?
2. Why is the value for ephemeral_storage so high for the pip service?
3. If the wof data for pip must be present, then it is not more sensible to run pip as a stateful set so
   each instance has its own wof sqlite database?
