Update parsers documentation

**Feature request**
It would be great to have compression for data.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_compression` with default `false`.

The issue names no files or tests, only parser documentation and the proposed `enable_compression` option. Start by locating the parser configuration entry point and how data is handled; done means compression is supported for the stated data path and the option defaults to `false`.
