does 1 batch interval of data generate one , one rdd in dstream regardless of how big quantity of data? yes, there 1 rdd per batch interval, produced @ every batch interval independent of number of records (that included in rdd -- there 0 records inside). if there wasn't, , rdd creation conditioned on number of elements, wouldn't have synchronous (micro-batching) streaming, rather form of asynchronous processing.

ok, seems it's hard me start thinking.. um.. functional way.. or asynchronous way. i rather new node.js, have many years of experience in c#, java, c++.. image have simple task. idea of task each line should executed after previous line finishes (blocking operations). normal approach in, let me say, c#. also, (that reason of post) let's imagine have 1 conditional line in our code. pseudocode following: f = openfile("aaa.txt") if f.readline(1) == "bbb" // read first line line = f.readline(2) // read second line else line = readline(3) // read third line database.insert(line) // store line in database, lets in mysql deletefile(f) pretty simple. now, understand, node.js uses non-blocking approach adding callbacks each function. so, simple task seems become nightmare me. if try reproduce code above, this: openfile(f, function() { readline(f, 1, function(line) { if line == "bbb" { readline(f,2, funct...

i keep simple- know if there way select values in column when never has null in column. example. b ----- ----- 1 7 2 7 null 7 4 9 1 9 2 9 from above set want 9 b , not 7 because 7 has null in a. wrap subquery , use in clause etc. part of pretty unique set , looking keep efficient. i should note purposes one-way comparison... returning values in b , examining a. i imagine there easy way missing, being in thick of things don't see right now. you can this: select * t t.b not in (select b t null); if want distinct b values, can do: select b t group b having sum(case when null 1 else 0 end) = 0; and, finally, use window functions: select a, b (select t.*, sum(case when null 1 else 0 end) on (partition b) nullcnt t ) t nullcnt = 0;

if accessing shared memory reading only, check condition if() block, should still lock mutex? e.g. mutex_lock(); if (var /* shared memory */) { } mutex_unlock(); is locking here needed , practice? if variable reading written concurrently, yes, should acquire lock on mutex. you read atomically if compiler provides necessary primitives that; either atomic features come c11 , c++11 or other language extension provided compiler. move mutex acquisition conditional, if wait until after test acquire mutex else may change between time test , time acquire mutex: if (example) { // "example" variable changed here thread. mutex_lock(); // condition might false! mutex_unlock(); } therefore, suggest acquiring mutex before conditional, unless profiling has pinpointed mutex acquisition bottleneck. (and in case tested variable larger cpu register -- 64-bit number on 32-bit cpu, example -- don't have option of delaying mutex acquisition withou...

i having difficulty in filtering table tab1 had fk key tab2 (tab1 had many 1 relation tab2) using orm.i wanted filter data in tab1 using fk column. used var items= entityload("tab1",{fk_col_name=value_variable}). now getting error: have attempted dereference scalar variable of type class java.lang.string structure members. let me share solution below if there better alternatives please share. the solution paved way through lot googling usual. seems because entityload() convenience function works against defined properties. entityload(), breedid not property. instead, breed property, being of type breed. around can use hql instead. so ref: http://blog.nictunney.com/2011/02/coldfusion-orm-filtering-on-composite.html

if create new windows uwp project in visual studio 2015 using out-of-the-box blank template find intellisense works without having build or refresh project. now, create custom project template based on blank template. find new project template creates project fine. however, new project not have intellisense until pacman (the nuget package manager) fetches microsoft.netcore.universalwindowsplatform package cache. after invoke pacman , fetch microsoft.netcore.universalwindowsplatform , new project still not have intellisense. is, until refresh project in solution explorer. @ point, in business. my question. setting in vstemplate.xml enables custom project template create project , work? say, can tell visual studio go ahead , run pacman , refresh project? there 1 requirement scenario. important custom template not have custom project wizard. not viable solution problem. believe can solved configuration, not code. please note, question involves nuget v3, not 2 or 1. do...
