MetadataFilter class final

Opaque filter criteria used by load balancers to restrict routing configuration to a limited set of load balancing proxies. Proxies and sidecars involved in load balancing would typically present metadata to the load balancers that need to match criteria specified here. If a match takes place, the relevant configuration is made available to those proxies.

For each metadataFilter in this list, if itsfilterMatchCriteria is set to MATCH_ANY, at least one of thefilterLabels must match the corresponding label provided in the metadata. If its filterMatchCriteria is set to MATCH_ALL, then all of its filterLabels must match with corresponding labels provided in the metadata.

An example for using metadataFilters would be: if load balancing involves Envoys, they receive routing configuration when values inmetadataFilters match values supplied in of their XDS requests to loadbalancers.
