Cherry-pick of PR #15859 to 7.x branch. Original message:
What does this PR do?
Update processors, output, and json parser to store the document ID in
@metadata._id
.Also add missing
document_id
to decode_json_fields processor, givenusers the chance to set the document id if the JSON document was
embedded in another JSON document.
Why is it important?
@metadata._id
.About the breaking change: The
document_id
setting on the JSON decoder has been introduced in 7.5, but overall effort on supporting event duplication was only finalized in 7.6. This means that the to@metadata._id
is a breaking change. But the feature wasn't much documented, while actual documentation on how to configure beats + ES for data duplication is planned for 7.6.Checklist
