in order to analyze the use of CPUs in different versions of different software or software, the relevant designer often needs to perform a stack performance analysis of the functions. Using timed interrupts to collect PC register values, function addresses, and the entire stack track is more efficient than regular sampling to get the data. Currently, tools such as OProfile, Gprof, and Systemtap Use this method to give detailed CPU usage reports. However, when dealing with complex statistical da

Requirements Scenario In a micro-service architecture, the way in which a requester of a service invokes a remote service is a problem that must be addressed. In the spring Cloud (Netflix) technology stack, each micro-service is exposed in the form of an HTTP rest interface, which normally requires an HTTP client to be used when executing a remote call, and then an HTTP request to the service. In fact, if you use Netflix's feign as an HTTP client, we

Kafka in versions prior to 0.8, the high availablity mechanism was not provided, and once one or more broker outages, all partition on the outage were unable to continue serving. If the broker can never recover, or a disk fails, the data on it will be lost. One of Kafka's design goals is to provide data persistence, and for distributed systems, especially when the cluster scale rises to a certain extent, the likelihood of one or more machines going do

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 introduced a new consumer API between 0.8 an
