what's cost/overhead of thread context switch? far know, there direct costs: saving , restoring context(generally,it includes general purpose registers , program counter) costs of thread scheduling(deciding thread next run) and there maybe indirect costs, such as: if thread switched out arranged run in cpu later, might re-load variables main memory(or other cpu via coherence protocol), cache read miss might occur. is there other indirect costs?

i'm trying rows column of type text[] contains value similar user input. what i've thought , done far use 'any' , 'like ' operator this: select * sometable '%someinput%' any(somecolum); but doesn't work. query returns same values query: select * sometable 'someinput' = any(somecolum); i've got result using unnest() function in subquery need query in clause if possible. why doesn't like operator work any operator , don't errors? thought 1 reason should any operator in right-hand of query, ... is there solution without using unnest() , if possible in where clause? it's important understand any not operator sql construct can used right of operator. more: how use instead of in in clause rails? the like operator - or more precisely: expression , rewritten ~~ operator in postgres internally - expects value left , pattern right. there no commutator operator (like there simple equali...

i created simple report has 5 columns (companyname, bought, sold, returned, total) looks like. companyname bought sold returned total with exception of company name, every value number. created simple queries bought, sold , returned. total used arithmetic in main query (basically sum of bought, sold, returned (returned negative)). problem came across companies, of columns (bought,sold,returned) null since ex: don't have returned when run report, doesn't show me value total. unless have values in three(bought sold , returned) - nothing gets displayed in total. don't want display zeros in report because clustered, there way me convert null 0 when calculation , hide report?

anybody knows whether unitils project still alive. on there pages last version 3.3 in maven repository 3.4.2.(actually there google cached version of pages version said 3.4.2) anyway there replacement project. kind of lack vivid community around , don't want bound dying project. unitils seems abandoned nowadays. project available on github here , can @ history , activity. anyways 2 cents... unitils has serious drawbacks: integrates many third-party libs (easymock, dbunit, spring, dbmaintainer, xmlunit, slf4j etc) , forces versions - serious drawback due being dependent on many 3rd party libraries, impossible keep date without company behind. unitils 4.0 developed since 06.2011 , planned release @ 01.2012, (01.2016) after 4 years still not released. dbunit for database-driven apps may seem interesting way go plain dbunit + spring-test or alternatively 3rd party tools: excilys/spring-dbunit comes handy @dataset annotation , actively developed on ...
