i receiving (streamed) data external source (over lightstreamer) c# application. c# application receives data listener. data listener stored in queue (concurrentqueue). queue getting cleaned every 0.5 seconds trydequeue datatable. datatable copy sql database using sqlbulkcopy. sql database processes newly data arrived staging table final table. receive around 300'000 rows per day (can increae within next weeks strongly) , goal stay under 1 second time receive data until available in final sql table. maximum rows per seconds have process around 50 rows. unfortunately, since receiving more , more data, logic getting slower in performance (still far under 1 second, wanna keep improving). main bottleneck (so far) processing of staging data (on sql database) final table. in order improve performance, switch staging table memory-optimized table. final table memory-optimized table work fine sure. my questions: is there way use sqlbulkcopy (out of c#) memory-optimized tables?

good day! i have problem every text change in text box, selected item in datagriview should copy value. have code lags when type(like fast) in textbox. is there better way w/o lagging? please help... here's have far: private void txttext_textchanged(object sender, eventargs e) { datagridview1[2, pos].value = txttext.text; } you may need limit number of events handled. requirements allow use textbox validated or lostfocus events instead? if not rx , throttle textchanged event. can achieved so: iobservable<eventpattern<eventargs>> observable = observable.fromeventpattern( txttext, "textchanged").throttle(timespan.frommilliseconds(500)) .subscribe(ep=> datagridview1[2, pos].value = txttext.text;); you throttle timer . timer mytimer = new timer(); mytimer.interval = 500; mytimer.tick = ontimertick; private void ontimertick(object o, eventargs e) { mytimer.stop(); datagridview1[2, pos].value = txttext....

i trying use dataframereader.load("table name") load hive table records , return dataframe . but dont want load entire records, wanted fetch records specific date (which 1 of field in hive table). if add condition in returned dataframe, load entire table first filter records based on date? because hive tables huge , partitioned based on date field. basically want achieve select * table date='date' using load method without loading entire table. recent versions of spark support feature called "predicate push-down". want: pushes, possible, sql clauses source. i'm not sure if predicate push-down works hive data source (it works parquet, jdbc , others sources). see does spark predicate pushdown work jdbc?
