Struct ChannelPartitionStream

Source

struct ChannelPartitionStream {
    schema: SchemaRef,
    receiver: Arc<Mutex<Option<InputReceiver>>>,
}

Expand description

A channel-backed partition is single-execution because receiving consumes its input. Plans that scan it more than once return an execution error.
