This extension enables Druid to parse the , a popular text-based timeseries metric serialization format.

The parser extracts these fields into a map, giving the measurement the key and the timestamp the key . The tag and measurement keys are copied verbatim, so users should take care to avoid name collisions. It is up to the ingestion spec to decide which fields should be treated as dimensions and which should be treated as metrics (typically tags correspond to dimensions and measurements correspond to metrics).

The field is an optional list of strings. If present, measurements that do not match one of the strings in the list will be ignored.
