agturley opened a new pull request, #11355: URL: https://github.com/apache/nifi/pull/11355
Allow the Index Field, Identifier Field, and Timestamp Field properties to reference a nested field with a "/"-delimited path (e.g. "@metadata/index"). A value with no "/" behaves exactly as before (top-level lookup), so existing flows are unaffected. When the corresponding Retain property is false, the extracted leaf is removed and any ancestor object left empty is pruned, so a transient envelope like "@metadata" is not indexed once its fields are consumed; parents that still have other fields are kept. Applies across NDJSON, JSON Array, and Single JSON, and all index operations. The NDJSON raw-bytes fast path is bypassed only when a nested path is configured, since the streaming scan only matches flat field names. Builds on NIFI-15985. <!-- Licensed to the Apache Software Foundation (ASF) under one or more --> <!-- contributor license agreements.
