reverse_connection.proto:20Configuration for a cluster of type REVERSE_CONNECTION.
optional cleanup_interval = 1
Time interval after which Envoy removes unused dynamic hosts created for reverse connections. Hosts that are not referenced by any connection pool are deleted during cleanup. If unset, Envoy uses a default of 60s.
string host_id_format = 2
Host identifier format string. This format string is evaluated against the downstream request context to compute the host identifier for selecting the reverse connection endpoint. The format string supports Envoy's standard formatter syntax, including: * ``%REQ(header-name)%``: Extract request header value. * ``%DYNAMIC_METADATA(namespace:key)%``: Extract dynamic metadata value. * ``%CEL(expression)%``: Evaluate CEL expression. * ``%DOWNSTREAM_REMOTE_ADDRESS%``: Downstream connection address. * ``%DOWNSTREAM_LOCAL_ADDRESS%``: Downstream local address. * Plain text and combinations of the above. Examples: * ``%REQ(x-remote-node-id)%``: Use the value of the ``x-remote-node-id`` header. * ``%REQ(host):EXTRACT_FIRST_PART%``: Extract the first part of the Host header before a dot. * ``%CEL(request.headers['x-node-id'] | orValue('default'))%``: Use CEL with fallback. * ``node-%REQ(x-tenant-id)%-%REQ(x-region)%``: Combine multiple values. If the format string evaluates to an empty value, the request will not be routed.
