(in 'pyspark') have rdd contains multiple dictionaries. each of these dictionaries, in turn, contain multiple dictionaries. looks this: label1 : {tag1, : count = 2, tag2: count = 3}, {tag2 : count = 3}, {tag3 : count = 1}, ... label2 : {tag1, : count = 2, tag3: count = 2}, {tag2 : count = 5}, {tag4 : count = 3}, ... . . given structure, i'd able "reduce" dictionaries result has following form: label1 : {tag1 : count = 2}, {tag : count = 6}, {tag3 : count = 1} ... label2 : {tag1 : count = 2}, {tag2 : count = 5}, {tag3 : count = 2}, {tag4 : count = 3}... . . . i have feeling resembles 'reduce' or 'combine' or 'groupby' having difficulty finding right function. can please point me function, in spark, might accomplish task? thanks! this should flatten iterator of dictionaries 1 big dictionary: def combine(iter): bigdict = dict() littledict in iter: key, value in littledict.iteritems(): big...

let's have: class foo { public int intpropertyinfoo { get; set; } public bar barpropertyina { get; set; } } class bar { public string stringpropertyinbar { get; set; } } then we'd instantiate foo object initializer: public static void main(string[] args) { var foo = new foo { intpropertyinfoo = 123, barpropertyina = // ommiting new , type name - why compile? { stringpropertyinbar = "something" } }; } the syntax of initializing barpropertyina baffles me, because code compiles without warnings and, when run, throws nullreferenceexception . don't recognize syntax, seems have same effect when used field, rather property. disassembling compiled code yields this: .method public hidebysig static void main(string[] args) cil managed { .entrypoint // code size 34 (0x22) .maxstack 3 .locals init ([0] class test.foo foo) il_0000: nop il_0001: newobj instance void...

i performing simple insert of few hundred rows, e.g.: insert foo select * bar the table has handful of secondary indexes. these indexes disabled query runs instantly. secondary indexes enabled, query takes seconds run, relatively high subtree cost. the issue every secondary index, database performs: physical operation : table spool logical operation : lazy spool where caches: all columns in destiation table (when needs values needs) multiple times values (rather once) while may interesting know why sql server (2008 r2 sp2) thinks needs this, need way make inserting 100 rows in live server not take 6 seconds. the really, really, horrible part every every table spool, sql server caches value of every column, every time: which burning logical io. without these problematic index updates, complete import of 60,000 rows happens in second or two with these indexes, complete import takes literally dozens of minute steps reproduce of course, real ...
