Flume ng Overview:

Flume Ng is a distributed, highly available, reliable system that collects, moves, and stores disparate amounts of data into a single data storage system. Lightweight, simple to configure, suitable for a variety of log collections, and supports failover and load balancing. Where the agent contains Source,channel and Sink, three have formed an agent. The duties of the three are as follows:

    • Channel: Interim storage, save all source component information
    • Sink: read from channel, delete information in channel after successful reading
