Improve models performance

**Feature request**
It would be great to have pagination for parsers.

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

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

No files or tests are named; start by locating the parser entry points and the configuration handling for existing options. Confirm how pagination should apply to parsers, then verify that enable_pagination defaults to false and that enabling it provides pagination in production use cases.
