Buffer¶
The buffer filter is used to stop filter iteration and wait for a fully buffered complete request. This is useful in different situations including protecting some applications from having to deal with partial requests and high network latency.
- v2 API reference
- This filter should be configured with the name envoy.buffer.
Per-Route Configuration¶
The buffer filter configuration can be overridden or disabled on a per-route basis by providing a BufferPerRoute configuration on the virtual host, route, or weighted cluster.
Statistics¶
The buffer filter outputs statistics in the http.<stat_prefix>.buffer. namespace. The stat prefix comes from the owning HTTP connection manager.
