Remove processor

The remove processor removes a field (Remove) or removes a field and all its nested fields (Remove by prefix) from your documents.

To remove a field:

1. Select Create → Create processor.
2. From the Processor menu, select Remove to remove a field or Remove by prefix to remove a field and all its nested fields.
3. Set the Source Field to the field you want to remove.

This functionality uses the Elasticsearch remove processor internally, but you configure it in Streamlang. Streamlang doesn’t always have 1:1 parity with the ingest processor options and behavior. Refer to Processor limitations and inconsistencies.
