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, a

In the previous blog, how to send each record as a message to the Kafka message queue in the project storm. Here's how to consume messages from the Kafka queue in storm. Why the staging of data with Kafka Message Queuing between two topology file checksum preprocessing in a

Storm in 0.9.3 provides an abstract generic bolt kafkabolt used to implement data write Kafka, let's take a look at a concrete example and then see how it is implemented. we use the code to annotate the way to see how the1. Kafkabolt's predecessor component is emit (can be Spout or bolt) Spout Spout = new Spout (New fields ("Key", "message")); Builder.setspout ("spout", spout); 2. Confi

Personal opinion: Big data we all know about Hadoop, but not all of it. How do we build a large database project. For offline processing, Hadoop is still more appropriate, but for real-time, relatively strong, the amount of data is large, we can use storm, then storm and what technology collocation, to be able to do a suitable project. We can refer to the following.You can read this article with the followi

Storm and Kafka single-host functions are well integrated, but some problems occur in the storm Cluster Environment and data processing performance. The test process and problems are briefly recorded as follows: Performance Indicator: at least 1 million of the information is processed per minute (about bytes in CSV format). The information is parsed and persiste

1. OverviewIn the Kafka combat-real-time log statistics process, we talked about storm issues, and we need to use storm to consume data from Kafka cluster when we're done with real-time log statistics, so I'll share a storm with you here alone. Cluster to build and deploy. H
