Test Data

This directory contains resources, such as test data, mounted into Druid indexer container at /resources. That name is chosen for backward compatibility with the previous IT version that mounted /src/test/resources to that mount point. See the indexer node in docker-compose.yaml for BatchIndex for the actual volume mount.

The many indexer specs expect data to be at /resources/data/batch_index/json/spec.json, where spec is the name of some ingest spec. The structure here was chosen to allow the existing specs to be reused without change.

Put data for the Indexer in this folder. Put files to be used by tests in /src/test/resources. That way, we only mount into the container the data which the server needs. Resources which tests need, such as queries, specs and other resources, are on the class path of the test, but are not visible to the server.

Paths within this folder are the same as the former /src/test/resources folder so that the many indexer specs don't have to change.
