Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.Problem/Motivation
I'm profiling a drush script that exports a large number of entities to CSV.
A lot of time is pent in normalizing the entities, even though only a subset of fields are required.
JSON:API's ResourceObjectNormalizer supports $context['sparse_fields'] to restrict the number of fields that need to be normalized.
However when normalizing to csv or other formats via drush or similar, there is no such equivalent. We can adopt the same approach.
Steps to reproduce
Proposed resolution
Support $context['sparse_fieldset'] in EntityNormalizer and ContentEntityNormalizer.
Remaining tasks
User interface changes
Introduced terminology
API changes
Data model changes

catchThis doesn't work in ComplexDataNormalizer because it's recursive, but it can work one level up in EntityNormalizer.

catchCoving both EntityNormalizer and ContentEntityNormalizer now, also added test coverage to their respective unit tests.
