First, Flume introduction Flume is a distributed, reliable, and highly available mass log aggregation system that enables customization of data senders in the system for data collection, while Flume provides the ability to simply process data and write to a variety of data-receiving parties (customizable). Design objectives: (1) Reliability When a node fails, the

This article is based on Kafka 0.81. Introduction Internet enough Company logs are everywhere, such as web logs, js logs, search logs, and monitoring logs. For the offline analysis (Hadoop) of these logs, wget rsync can meet the functional line requirements despite the high labor maintenance cost. However, for the real-time analysis requirements of these logs (such as real-time recommendation and monitoring systems), it is often necessary to introduc

, Sendfile Kafka consumption does not lose the mechanism. Producer, broker, consumer. Kafka consumer data is globally ordered. The individual partition is orderly, the global order violates the design original intention.

high level consumer instances belongs to a consumer group, which, if unspecified, belongs to the default group. Push vs. Pull As a messaging System,kafka follows the traditional approach, selecting producer to broker push messages and consumer from broker pull messages. Some logging-centric system, such as Facebook's scribe and Cloudera's flume, adopt very different push modes. In fact, both the push mode
