Kafka is a distributed publishing subscription messaging system. Developed by LinkedIn and has become the top project in Apache in July 2011. Kafka is widely used by many companies such as LinkedIn, Twitte, etc., mainly for: Log aggregation, Message Queuing, real-time monitoring and so on.Starting with version 0.8, Kafka supports intra-cluster replication for inc

The partitioned table does not differ from the unpartitioned table in the execution of the DML statement.5 When partitioning a table, you must speci

The semantics of these partitions are defined by the producer, which specifies which partition each message b
I. Some concepts and understandings about Kafka
Kafka is a distributed data flow platform that provides high-performance messaging system functionality based on a unique log file format. It can also be used for large data stream pipelines.
Kafka maintains a directory-based message feed, called Topic.
The project called the release of the message to topic was a
Kafka is a distributed Message System Based on publishing and subscription. It has the following features.
1. Provides message persistence and access performance for a constant time.
2. high throughput. A cheap commercial machine can transmit up to messages per second.
3. Supports message partitions, distributed consumption, and ordered messages in the Kafka server.
4. Supports horizontal scaling.
5. Suppor
High throughput of Kafka
As the most popular open-source message system, kafka is widely used in data buffering, asynchronous communication, collection logs, and system decoupling. Compared with other common message systems such as RocketMQ, Kafka ensures most of the functions and features while providing superb read/write performance.
