Conversionsjson_normalizations Property |
An array of JSON normalization operations, including one or more of the following:
copy — Copies the value of the source_field to the destination_field. If the destination_field already
exists, the value of the source_field overwrites the original value of the destination_field.
move — Renames (moves) the source_field to the destination_field.If the destination_field already exists,
the value of the source_field overwrites the original value of the destination_field. Rename is
identical to copy, except that the source_field is removed after the value has been copied to the
destination_field. It is the same as a copy followed by a remove.
merge — Merges the value of the source_field with the value of the destination_field. The
destination_field is converted into an array if it is not already an array, and the value of the
source_field is appended to the array. This operation removes the source_field after the merge. If the
source_field does not exist in the current document, the destination_field is converted into an array if
it is not already an array. This is ensures the type for destination_field is consistent across all
documents.
remove — Deletes the source_field. The destination_field is ignored for this operation.
remove_nulls — Removes all nested null (blank) leaf values from the JSON tree. The source_field and
destination_field are ignored by this operation because remove_nulls operates on the entire JSON tree.
Typically, remove_nulls is invoked as the last normalization operation; if it is invoked, it can be
time-expensive. The array also lists the source_field and destination_field for each operation. If no
JSON normalization operations are specified, the method returns an empty array.
