kafka manager

SummaryThis paper mainly introduces how to use Kafka's own performance test script and Kafka Manager to test Kafka performance, and how to use Kafka Manager to monitor Kafka's working status, and finally gives the Kafka performanc

Recently want to test the performance of Kafka, toss a lot of genius to Kafka installed to the window. The entire process of installation is provided below, which is absolutely usable and complete, while providing complete Kafka Java client code to communicate with Kafka.

If the cache is lost, or if the program instance is moved to a different location, the local state can be rebuilt. You can use Kafka streams this library in your program, and then

Kafka ---- kafka API (java version), kafka ---- kafkaapi Apache Kafka contains new Java clients that will replace existing Scala clients, but they will remain for a while for compatibility. You can call these clients through some separate jar packages. These packages have little dependencies, and the old Scala client w

Sina Weibo: intsmaze Liu Yang Ge : Intsmaze Create a kafka topic named intsmazX and specify the number of partitions as 3. Use kafkaspout to create a consumer instance for this topic (specify the path where metadata is stored in zookeeper as/kafka-offset, and specify the instance id as onetest). Start storm and o

system, and the Kafka community is not very supportive of this. If your data sources have been identified and do not require additional coding, then you can use the sources and sinks provided by Flume, and conversely, if you need to prepare your own producers and consumers, then you need to use Kafka. Flume can process data in real time in interceptors. This feature is useful for filtering data.

on the subject or content. The Publish/Subscribe feature makes the coupling between sender and receiver looser, the sender does not have to care about the destination address of the receiver, and the receiver does not have to care about the sending address of the message, but simply sends and receives the message based on the subject of the message. Cluster (Cluster): To simplify system configuration in point-to-point communication mode, MQ provides a Cluster (cluster) solution. A cluster is

That is to say, this FetchRequest contains a data segment of my-working-topic Partition 15. The data starting position is 0 and the data size is 1048576 (1024*1024) ). However, we have just analyzed the data synchronization threads of four partitions in my-working-topic 21, 15, 3, and 9 that have just been stopped by the manager, in a Data Syn
