Flume is a data management tool that is distributed, reliable, and flexible. It can aggregate and move huge amounts of data from various data sources. Its architecture is similar to that of the Hadoop Distributed File System (HDFS). It consists of an agent that helps the client communicate with the HDFS. This agent consists of a source, channel, and sink. The source extracts the unstructured data from the client and is based on an event-driven model. The channel is a buffer queue that temporarily stores the data, controls the speed, and prevents the loss of packets. The sink is the final data that can be stored in the HDFS. This is how Flume does data management.
