i have code , wan work against javardd instead of rdd i'm doing conversion here. know performance impact of transformation specialy when i'm dealing gbs of data. rdd<string> textfile = sc.textfile(filepath, 2); javardd<string> javardd = textfile.tojavardd(); this wide or narrow transformation ? difference between javardd , rdd ? there's no significant performance penalty - javardd simple wrapper around rdd make calls java code more convenient. holds original rdd ad member, , calls member's method on method invocation, example (from javardd.scala ): def cache(): javardd[t] = wraprdd(rdd.cache()) wraprdd boils down new javardd[t](rdd) , performance penalty creating thin java object every method invocation, that's entirely negligible it's not done per element in rdd, once entire object.

optional chaining returns always optional value. to reflect fact optional chaining can called on nil value, result of optional chaining call optional value, if property, method, or subscript querying returns nonoptional value. the swift programming language why heck in playground type not optional? let stringoptempty: string? = "" stringoptempty?.isempty // true stringoptempty?.isempty.dynamictype // bool.type but following code is let isok = stringoptempty?.isempty.dynamictype isok.dynamictype // optional<bool.type>.type tldr; the playground sidebar/column dynamically resolve expressions in playground, values assigned variables (mutables/immutables) or "free-floating" non-assigned values. your first example applies dynamictype value , resolve type of specific value ( true.dynamictype : bool.type ). your second example, on other hand, applies dynamictype variable (an immutable, i'll use variable here differ val...

quote "swift apprentice second edition page 225": properties(computed) hold values can , set. methods perform work quote "swift official document": in addition stored properties, classes, structures, , enumerations can define computed properties, not store value one says "store", 1 says "hold". bit confused computed properties, computed properties not store value means? means system not assign memory space save value , hold it. what's hold means? can't hold in nowhere, need maybe box hold something, isn't it? simple example documentation struct cuboid { var width = 0.0, height = 0.0, depth = 0.0 var volume: double { return width * height * depth } } volume never stored in memory. whenever getter called result of multiplication returned dynamically math operation in local scope. the official apple documentation not use term hold @ all.
