A brief discussion on using FlinkKafkaProducer to implement Exactly Once semantics on the sink side
Abstract In some important flink data processing scenarios, it is necessary to implement Exactly Once data processing. Exactly Once means that when flink processes data, it can ensure that data is not lost and data is not repeated. The entire flink processing link is roughly divided into three links: Source -> Transform -> Sink. Selecting […]

[Server-side performance test] Performance test implementation process!
Performance testing uses automated testing tools to simulate a variety of normal, peak, and abnormal load conditions to test various performance indicators of the system. My definition of performance testing clearly describes the methods and processes of performance testing: Performance testing aims at system performance indicators, establishes performance testing models, formulates performance testing plans, develops […]

Not fully considering structure + dp and structure: 1107T2
http://cplusoj.com/d/senior/p/SS231107B It is found that the reverse operation will modify a bunch of numbers, but what if we only focus on some of them? Assume we have constructed [ 1 , i ? 1 ] [1,i-1] [1,i?1], we now try to construct [ i , n ] [i,n] [i,n], our operable range is [ i […]

Strange things encountered in side missions – concurrent requests
Concurrent requests refer to the situation where one or more requests are always sent out at the same time. It does not mean that these requests are sent exactly at the same time, but within a period of time, these requests may be sent one after another due to small differences in time. These requests […]
