A GitHub project is recently completed: Storm-hbase, which is a combination of Twitter storm and Apache hbase. It uses hbase cluster as the storm spout data source. Currently, it is only a preliminary implementation, it will be further improved in the future. Hbasespout reads stream data from hbase cluster continuously based on the timestamp range [start_timest

Preface What is storm,storm to do, a simple description that you can understand as a "quasi-real-time" Hadoop,hadoop is dedicated to offline data processing, while Storm makes up for Hadoop's shortcomings in this area, he is a real-time data processing platform. As for the various origins of storm, it is not a nonsens

1. OverviewIn the "Kafka combat-flume to Kafka" in the article to share the Kafka of the data source production, today for everyone to introduce how to real-time consumption Kafka data. This uses the real-time computed model--storm. Here are the main things to share today, as shown below: Data consumption Storm calculation Preview Next, we start sharing today's content.2.

IntroductionThese days in order to optimize the original data processing framework, compare the system to learn some of the storm's content, sorting out the experience1. Storm provides a data-processing idea that does not provide a specific solutionThe core of storm is the definition of topo, and Topo carries all the business logic, and we orchestrate the private business implementation logic based on the s

The installation and configuration of the Twitter Storm standalone version have been clearly stated in the previous note:This article mainly describes how to expand to a cluster based on the standalone version.All the machines in the cluster need to install the tool software as needed in the standalone version:Python, zookeeper, zeromq, jzmq, and stormInstall the tool one by one described in the installation of the standalone edition tutorial.The diff

Storm is a distributed stream processing system that uses anchor and ACK mechanisms to ensure that all tuples are successfully processed. If a tuple is faulted, it can be re-transmitted, but how do you ensure that the wrong tuple is processed only once? Storm provides a set of transactional components transaction topology to solve this problem.Transactional topology is no longer maintained and is implemente

Apache Storm reads the raw stream of real-time data from one end and passes it through a series of small processing units and outputs processing/useful information at the other end. 　　 Describes the core concepts of Apache storm. 　　 640?wx_fmt=pngwxfrom=5wx_lazy=1 　　 Now let's take a closer look at the components of Apache storm- 　　 Component description 　　 Tuple

From the big to the small words we see it has so 5 levels, the simplest storm is a cluster, cluster is a level, the second level is a relatively clear meaning, is the supervisor,supervisor corresponding to the level is a host, is a node , is a machine this level, and then a machine it has a lot of worker,worker is actually corresponding to the process level, is the progress level, the machine runs a few processes, the provision of 4 workers, on 4 proc

Recently completed a GitHub project: Storm-hbase, the project is a combination of Twitter Storm and Apache HBase, it uses HBase cluster as Storm spout data source, is only a preliminary implementation, the follow-up will be further improved. Hbasespout reads stream data continuously from HBase cluster according to the timestamp range [Start_timestamp, Stop_timest

1. Heartbeat detection, store supervisor and worker heartbeat (including their status), so that Nimbus can monitor the status of the entire cluster, thus restarting some of the dead worker; 2. Submit a Task 3. Store all state information for the entire cluster for the UI display 4. Storm's storage structure on ZK /-{storm-zk-root}--The root directory of storm on zookeeper (default =/

When I visited a software forum recently, see About the Storm audio and video installation parameters of the post, originally in the Storm audio and video release of the 6.0 version, many Storm fans found that it added new features, but also bundled more rogue software, so the Storm fan will be used to avoid bundled ro

Fault Tolerance of Storm This article describes the design details of Storm Fault Tolerance: How the Worker, node, Nimbus, or Supervisor is Fault tolerant, and whether Nimbus has a single point of failure. This blog is about the translation of the Fault-Tolerance article on the Storm official website. I have been paying attention to

Today I continue to learn some basic knowledge about storm and have a basic understanding of its usage. Fortunately, it is not too difficult, if you understand the hadoop mapreduce model, it is similar. First, I understand some concepts when I understand the
