rename processor specifies a list of fields to rename. Under the
key, each entry contains a
from: old-key and a
to: new-key pair, where:
fromis the original field name. It’s supported to use
fromand rename keys in the event metadata instead of event fields.
tois the target field name
rename processor cannot be used to overwrite fields. To overwrite fields
either first rename the target field, or use the
drop_fields processor to drop
the field and then rename the field.
You can rename fields to resolve field name conflicts. For example, if an
event has two fields,
b is a subfield of
scalar values results in an Elasticsearch error at ingest time. The assignment
"c.b": 2} would result in an error because
c is an object and cannot be
assigned a scalar value. To prevent this conflict, rename
before assigning values.
