[extensions.rate_limit_descriptors.expr.v3.Descriptor proto]
The following descriptor entry is appended with a value computed from a symbolic Common Expression Language expression. See attributes for the set of available attributes.
("<descriptor_key>", "<expression_value>")
{
"descriptor_key": "...",
"skip_if_error": "...",
"text": "...",
"parsed": "{...}"
}
- descriptor_key
(string, REQUIRED) The key to use in the descriptor entry.
- skip_if_error
(bool) If set to true, Envoy skips the descriptor if the expression evaluates to an error. By default, the rate limit is not applied when an expression produces an error.
- text
(string) Expression in a text form, e.g. “connection.requested_server_name”.
