running shark. In this architecture, Spark replaces Hadoop as an ETL, while Shark replaces the commercial Bi/olap tool, taking on reports/dashboards and interactive/ad hoc queries, while interfacing with desktop bi tools such as tableau. The current spark cluster deployed on Yahoo has 112 nodes, 9.2TB of memory, and is considering adding SSDs. Tim introduces the future of work. First of all, Pig/mapreduce will take the place entirely, with all the ET

Reverse basic Finding important/interesting stuff in the code (2) zing Chapter 2 Call assert Sometimes, the emergence of assert () macro is also useful: Usually this macro will leak the source file name, row number and condition. The most useful information is included in the assert condition, from which we can infer the variable name or struct name. Another useful information is the file name. We can infer the type of code used. It is also possible to identify a famous open source library by fi

Don't optimize it! Let the compiler do it !, Optimize the Compiler

Don't optimize it! Let the compiler do it !, Optimize the Compiler We often perform optimization on our own when writing code. In fact, most cases are unnecessary because the compiler is much smarter than you think! The example below demonstrates that, This is a kind of recursive writing. Many veterans will tell you that writing performance is low and loop should be used. Int rfact (int x) { Int rval; If (x Return 1; Rval = rfact (x-1 ); Return rval * x; } I don't think everyone has any object
