This file provides a sample app for loading data into FDB.
To use it to load data into one of the sample clusters in this repo,
you can build the image by running `docker build -t fdb-data-loader sample-apps/data-loader`,
and then run the data loader by running `kubectl apply -f sample-apps/data-loader/job.yaml`

SimpleDoc also provides a powerful plugin capability that allows multiple levels
of plugins to manipulate the logical-to-physical mapping of operations.
The use of plugins is illustrated with an Index plugin that permits an
application to create indexes on documents using a pattern-matching syntax.
