I have posted the second batch of Elasticsearch lab exercises using the Olympic events dataset.

This set of exercises will get the data into a new index in a nice, clean state, ready for analysis in the next round.

There are fewer questions in this batch as getting the ingest pipelines configured can be quite fussy. There are different ways of writing the pipelines; leveraging many processors is common but some Developers choose to do a lot of work in a script processor. You can choose your own style - only a correct output is required.
