Documentation

Overview

Package input defines consumers for aggregating data from a variety of sources. All consumer types must implement interface input.Type.

If the source of a consumer is given assurances of message receipt then the consumer must ensure that all messages read from a source are propagated to a reader before shutting down gracefully. For example, a ZMQ subscriber model based consumer would not need to provide such ensurance, a HTTP POST based consumer, however, would be expected to propagate any requests where a 200 OK message has been returned.
