this question regarding behavior of cassandra select * query. it's more understanding, know normaly should not execute such query. assuming have 4 nodes rf=2. following table (column family): create table test_storage ( id text, created_on timestamp, location int, data text, primary key(id) ); inserted 100 entries table. now select * test_storage via cqlsh. doing query multiple times different results, not entries. when changing consistency local_quorum complete result. why so? assumed, despite performance, consistency 1 entries since must query whole token range. second issue, when add secondary index in case location, , query select * test_storage location=1 random results wiht consistency one. , correct results when changing consistency level local_quorum. here don't understand why happens? when changing consistency local_quorum complete result. why so? welcome eventual consistency world. understand it, read slides: http://www.sl...

i'm using laravel 5 , postgres. there table has 2 columns 'start_date' , 'end_date'. want create index can check if date falls in between two. i'm using following code that $table->date ( 'start_date' ); $table->index('start_date'); $table->date ( 'end_date' ); $table->index('end_date'); but saw there option create compound index too. my question best way create indexes above scenario? depends on queries are. while other databases mysql can use 1 index per table in situations postgresql can use more one. thus if have 2 separate indexes on start_date , end_date chances both used if close has conditions both columns. note there isn't guarantee both indices or 1 of them might used. example if have few rows faster retrieve data directly without referring index. in situation having composite index wouldn't of use either. if have other queries involve 1 of 2 columns, again better off 2 separ...

is possible have dynamic memory allocation in string read scanf without first declaring array? it not possible dynamically allocate memory string after having read scanf , scanf needs pointer. means must allocate memory first, in order give argument scanf . you can following example : char *str; str = malloc(x*sizeof(char)); //where x number of characters want allocate if (str != null) int result = scanf("%s", str); in other words, pass allocated pointer scanf . note : should careful input give, might cause buffer-overflow if give string larger allocated space.

i have question believe quite simple, don't know proper way it. basically, program able identify words pattern in it, , if so, extract what's before pattern. the pattern be, in case /f , @ end of word, , extract what's before. for example, if program finds 21/f , identify match , extract 21 . if word 21/fudge , wouldn't anything. do know way match @ specific position in word? i do: if str "*/f" before=left(str, len(str)-len("/f")) else 'no match! end if
