• string stat_prefix = 1

  The prefix to use when emitting :ref:`statistics <config_network_filters_local_rate_limit_stats>`.

• optional type.v3.TokenBucket token_bucket = 2

  The token bucket configuration to use for rate limiting connections that are processed by the filter's filter chain. Each incoming connection processed by the filter consumes a single token. If the token is available, the connection will be allowed. If no tokens are available, the connection will be immediately closed. .. note:: In the current implementation each filter and filter chain has an independent rate limit, unless a shared rate limit is configured via :ref:`share_key <envoy_v3_api_field_extensions.filters.network.local_ratelimit.v3.LocalRateLimit.share_key>`. .. note:: In the current implementation the token bucket's :ref:`fill_interval <envoy_v3_api_field_type.v3.TokenBucket.fill_interval>` must be >= 50ms to avoid too aggressive refills.

• optional config.core.v3.RuntimeFeatureFlag runtime_enabled = 3

  Runtime flag that controls whether the filter is enabled or not. If not specified, defaults to enabled.

• string share_key = 4

  Specifies that the token bucket used for rate limiting should be shared with other local_rate_limit filters with a matching :ref:`token_bucket <envoy_v3_api_field_extensions.filters.network.local_ratelimit.v3.LocalRateLimit.token_bucket>` and ``share_key`` configuration. All fields of ``token_bucket`` must match exactly for the token bucket to be shared. If this field is empty, this filter will not share a token bucket with any other filter.
