helps improve System Fault Tolerance: if a machine crashes, no messages will be lost because they are stored in other machines. In addition, if the second job consumes messages slowly or stops for some reason, the first task does not affect: the disk buffer can accumulate messages until the second task is faster. By partitioning a topic, data stream processing is split into tasks and executed concurrently on multiple machines, so that samza has a high message throughput. By combining yarn and K

the RDD. For most files on HDFs, each block of data generates a inputsplit that is approximately mb/128 MB in size. In approximate cases, the block boundaries of data on HDFs are counted in bytes (64MB blocks), but when the data is processed, it is sliced by record. For a text file, the characters that are sliced are line breaks, and for sequence files, it ends with blocks and so on. The more special is the compressed file, because the entire file is compressed, so can not be sliced by the line

In the past year, the front-end technology development, the most dazzling star is react.React itself involves only the UI layer, and if you build large applications, you must match a front-end frame. In other words, you must learn at least two things in order to basically meet the needs: React + front-end frame.Facebook is officially using the Flux framework. This article describes how to use Flux to organize your code and arrange internal logic on React basis, making your application easier to

Service:The Object service accesses the primary portal of the database and returns the data that is accessed. It is primarily responsible for specific things, such as getting data from the entity client data provider (its next layer) and converting it to a solid object.Entity Client Data Provider:The primary responsibility of this layer is to translate queries provided by LINQ to Entities or entity SQL into specific databases to understand the queries that are executed. It uses the ADO data pro
