string metadata_namespace = 1
The namespace — if this is empty, the filter's namespace will be used.
string key = 2
The key to use within the namespace.
oneof value_type
- google.protobuf.Value value = 3
  The value to pair with the given key. When used for on_present case, if value is non-empty it'll be used instead of the the value of the JSON key. If both are empty, the the value of the JSON key is used as-is. When used for on_missing/on_error case, a non-empty value must be provided. It ignores ValueType, i.e., not type casting.
ValueType type = 4
The value's type — defaults to protobuf.Value.
bool preserve_existing_metadata_value = 5
False if we want to overwrite the existing metadata value. Default to false.

repeated Rule rules = 1
The list of rules to apply.
repeated string allow_content_types = 2
Allowed content-type for json to metadata transformation. Default to ``{"application/json"}``. Set ``allow_empty_content_type`` if empty/missing content-type header is allowed.
bool allow_empty_content_type = 3
Allowed empty content-type for json to metadata transformation. Default to false.
optional type.matcher.v3.RegexMatcher allow_content_types_regex = 4
Allowed content-type by regex match for json to metadata transformation. This can be used in parallel with ``allow_content_types``.

A Rule defines what metadata to apply when a key-value is present, missing in the json or fail to parse the payload.

repeated Selector selectors = 1
Specifies that a match will be performed on the value of a property. Here's an example to match on 1 in {"foo": {"bar": 1}, "bar": 2} selectors: - key: foo - key: bar
optional KeyValuePair on_present = 2
If the attribute is present, apply this metadata KeyValuePair.
optional KeyValuePair on_missing = 3
If the attribute is missing, apply this metadata KeyValuePair. The value in the KeyValuePair must be set.
optional KeyValuePair on_error = 4
If the body is too large or fail to parse or content-type is mismatched, apply this metadata KeyValuePair. The value in the KeyValuePair must be set.
