i watching 1 of cassandra videos on datasax academy. 1 concept talk lot query driven modelling. makes sense when know queries upfront in killrvideo example. however, in big data cases, hope not 1 think barely know kind of queries analysts perform on data 5 months or 1 year down road. if case, best practices storing data? guess advanced querying of such data, end loading data spark. have consider @ storage time avoid operational troubles , troubles @ retrieval time? retrieval approaches less problematic? cassandra database analytics use cases, not ad-hoc analaytics (only 1 report , query never perform again stuff). for use cases hadoop cluster better option your. (maybe parquete on hadoop) if see queries perform on , on again, cassandra friend. can use cassandra 50 70% of use cases. column keys , secondary indizies can perform wide spectrum of queries. go analytics guys , ask them need. then: create tables :)

i've learning reactjs while now. 1 of thing puzzles me why reactjs uses immutability in many aspects props, elements etc. there specific reason this? philosophy behind this? when try add new property props i'm getting below error. uncaught typeerror: can't add property me, object not extensible react uses immutability obvious performance reasons. example idea whenever setting state , dont mutate state clone part of , update state for example this.state = { entries: [1,2,3] } you should do this.state.setstate({ entries: this.state.entries.slice().push(9); //not this.state.entries.push(9) }) performance gains achieved when use shouldcomponentupdate in shouldcomponentupdate can compare references , not due deep checking shouldcomponentupdate(prevstate,newstate){ return prevstate.entries != newstate.entries }
