kafka producer and consumer

thread that uses a class of resources (represented by class goods) is called the consumer consumer, and the thread that produces the same resource is called producer. To enable consumer and producer to work together, they should follow the following rules:(1) The

First, why use producers and consumers?In the world of threads, the producer is the thread of the production data, the consumer is the thread of consuming data, in the multi-threaded development, if the producer processing speed is very fast, and the consumer processing speed is very slow, then the

condition variable. if the condition variable is statically allocated, you can also use a macro to define PTHEAD_COND_INITIALIZER for initialization. use pthread_cond_destroy to destroy the condition variable. if the condition variable is successfully returned, 0 is returned. A condition variable is always used with a Mutex. A thread can call pthread_cond_wait to block the wait on a condition variable. this function performs the following three steps: 1. release Mutex 2. blocking wait 3. when a

read-write threads do not require mutual exclusion, is the producer of consumer issues, if there is no mutual exclusion between read read, each resource can be used by multiple read threads together, There is a requirement for mutual exclusion between writes (each resource is used only by one write thread), and the read-write thread also requires mutual exclusion (no writing when reading, no reading when w
