Local rate limit

    Note

    The token bucket is shared across all workers, thus the rate limits are applied per Envoy process.

    Note

    The local rate limit filter applies a rate limit to incoming connections that are processed by the filter’s filter chain. Each connection processed by the filter utilizes a single token, and if no tokens are available, the connection will be immediately closed without further filter iteration.

    Note

    In the current implementation each filter and filter chain has an independent rate limit.

    Every configured local rate limit filter has statistics rooted at local_ratelimit.<stat_prefix>. with the following statistics:

    The local rate limit filter can be runtime feature flagged via the enabled configuration field.
