Enum vector::components::validation::ResourceDirection

source · 
pub enum ResourceDirection {
    Pull,
    Push,
}
Expand description

Direction that the resource is operating in.

Variants§

§

Pull

Resource will have the component pull data from it, or pull data from the component.

For a source, where an external resource functions in “input” mode, this would be the equivalent of the source calling out to the external resource (HTTP server, Kafka cluster, etc) and asking for data, or expecting it to be returned in the response.

For a sink, where an external resource functions in “output” mode, this would be the equivalent of the sink exposing a network endpoint and having the external resource be responsible for connecting to the endpoint to grab the data.

§

Push

Resource will push data to the component, or have data pushed to it from the component.

For a source, where an external resource functions in “input” mode, this would be the equivalent of the source waiting for data to be sent to either, whether it’s listening on a network endpoint for traffic, or polling files on disks for updates, and the external resource would be responsible for initiating that communication, or writing to those files.

For a sink, where an external resource functions in “output” mode, this would be the equivalent of the sink pushing its data to a network endpoint, or writing data to files, where the external resource would be responsible for aggregating that data, or read from those files.
