case: Wait for any of the replica in the ISR to "live" and choose it as leader. Choose the first "live" replica (not necessarily in the ISR) as leader. This requires a simple tradeoff between usability and consistency. If you must wait for the replica in the ISR to come over, the unavailable time may be relatively long. And if all the replica in the ISR are unable to "live" or the data is lost, the partition will never be available. Choose the first "live" replica as Leader, a

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. Here you have to spit, most of the online artic

Use a dataflow-like model to handle windowing problems with scrambled data Distributed processing, and has a fault-tolerant mechanism, can be quickly implemented failover There is the ability to re-process the data, so when your code changes, you can recalculate the output. There is no time to roll the deployment. For those who want to skip the preface and want to read the document directly, you can go directly to Kafka Streams D

Note: Spark streaming + Kafka integration Guide Apache Kafka is a publishing subscription message that acts as a distributed, partitioned, replication-committed log service. Before you begin using Spark integration, read the Kafka documentation carefully. The Kafka project

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

feasible, but at least we have come up with a feasible solution, isn't it.We spent a lot of time studying the relationship between kafka and the network card, but suddenly looked back and found that we had a big bend without knowing it. In the final analysis, we want to solve the network bandwidth problem. Instead, we can link ourselves to kafka. Since we can build a pseudo cluster on a machine, so why not

GuaranteeKafka's Advanced API provides the following guarantees:☆ messages are sent to a specific topic partition by the producer, and messages are appended to this partition in the order in which they are sent. For example, if M1 and M2 messages are sent by the same producer, M1 is sent first, the M1 offset will be smaller and earlier in the log than M2.☆ Consumer Instances View records in the order in w
