java.lang.Object org.apache.flume.source.AbstractSource org.apache.flume.source.AvroSource
public class AvroSource
A Source
implementation that receives Avro events from clients that
implement AvroSourceProtocol
.
This source forms one half of Flume's tiered collection support. Internally,
this source uses Avro's NettyTransceiver to listen for, and handle
events. It can be paired with the builtin AvroSink to create tiered
collection topologies. Of course, nothing prevents one from using this source
to receive data from other custom built infrastructure that uses the same
Avro protocol (specifically AvroSourceProtocol
).
Events may be received from the client either singly or in batches.Generally,
larger batches are far more efficient, but introduce a slight delay (measured
in millis) in delivery. A batch submitted to the configured Channel
atomically (i.e. either all events make it into the channel or none).
Configuration options
Parameter | Description | Unit / Type | Default |
---|---|---|---|
bind | The hostname or IP to which the source will bind. | Hostname or IP / String | none (required) |
port | The port to which the source will bind and listen for events. | TCP port / int | none (required) |
