can call stored procedures in parallel way increase execution speed. eg: have 3 stored procedures extract data 3 master tables , load/insert single source table.currently having 3 procedures : call sp_1(); call sp_2(); call sp_3(); and running in sequential way insert records takes more time. there way run these procedures in parallel way improve execution time , speed process..kindly me possible work around this. q: can call stored procedures in parallel way increase execution speed. a: short answer no. there's no built-in mechanism (in mysql) make stored procedure run "in parallel". achieve parallel processing, application need designed that, making use of multiple connections mysql, splitting processing chunks can run in parallel, , coordinating processes. as far "increase execution speed", you'd need first identify causing slowness. if issue storage i/o, parallel-izing process not going increase execution speed. if procedure ...

if does, how can archive performance when graph needs modifying? mean modifying add or remove vertices or edges. yes, pregel allows structure modified. called mutations. presented in section 3.4 topology mutations of paper. according paper, available @ ( http://kowshik.github.io/jpregel/pregel_paper.pdf ): "multiple vertices may issue conflicting requests in same superstep (e.g., 2 requests add vertex v , different initial values). use 2 mechanisms achieve determinism: partial ordering , handlers. as messages, mutations become effective in superstep after requests issued. within superstep removals performed first, edge removal before vertex removal, since removing vertex implicitly removes of out-edges. additions follow removals, vertex addition before edge addition, , mutations precede calls compute(). partial ordering yields deterministic results con icts. the remaining conflicts resolved user-defined handlers. if there multip...

i may going entirely wrong open , suggestions. trying require statustype parameter in this: response(statustype.submit, message); to limited set of types return constant string value. far have come solution: public class response { private statustype _status; response(statustype status, string message) { _status = status; } public string status { { return enum.getname(typeof(statustype), _status); } } } public enum statustype { fail, success, response, confirm } but realize enum parameter weak-typed , allow me enter string value instead. can me? have feeling enum not solution i'm not sure of way. based on comments, getting error when using class vb project. when option strict turned off, vb try "helpfully" convert objects between "compatible" types. hides mistakes , causes hard track down errors. recommend turning 'option strict` on when deve...
