What are the three main components of Flume?

The three main core components of Flume are:

1. Source is responsible for retrieving data from external sources, such as log files or network data, and passing the data to the next component in Flume. It can be a single source or a combination of multiple sources.
2. Channel in Flume serves as a buffer to store data retrieved from a Source. It allows multiple Sources to write data to the Channel in parallel, while also allowing multiple Sinks to read data from the Channel in parallel. The Channel can be a in-memory queue or a disk-based queue.
3. The Sink is responsible for sending data from the Channel to specific destinations such as Hadoop HDFS, Kafka, HBase, and more. It can write data to a single destination or replicate data and write to multiple destinations.

These three core components working together form the data flow pipeline of Flume.
