elasticsearch performance test

the performance of ES. At the same time, assuming that the machine 1 has a routing attribute a document, Machine 2 has a routing attribute B document, then I in the query when the target route attribute is a, even if the machine 2 failure paralysis, the machine 1 structure is not a great influence, so do the query under the disaster situation also proposed a solution. The so-called route, in essence, is a split-bucket (bucketing) operation. Of course

Elasticsearch performance optimization is mainly divided into 4 aspects.First, Server Deployment1. Add 1-2 servers for load Balancing section Point There are 2 parameters in the Elasticsearch configuration file: Node.master and Node.data.When used together, these two parameters can help provide server performance. Node

Collect Elasticsearch performance parameters in Bigdesk and save to database or elk for long-term monitoring.

Label:Poptest is the only training institute for developing Test and development engineers in China, aiming at the ability of the trainees to be competent in automated testing, performance testing and testing tools development. In Poptest's LoadRunner training, in order to improve the performance of students experience, add a lot of server optimization knowledge,

Performance Test Definition: Through a certain tool combined with the corresponding testing methods, the application of the deployment system test, found that the system application of the internal code logic problems and application of the deployment of machine hardware resource bottlenecks and application deployment architecture There are architectural errors,

Chapter 7: Live Video cloud SDK Performance Test Model and sdk performance test There are a lot of technical articles on live broadcasting, and there are not many systems. We will use seven articles to give a more systematic introduction to the key technologies of live video in all aspects of the current hot season, an
