How to process historical data stream in response to dynamic queries in Flink -


i'm trying create datastreams dynamically @ run-time union of historical , real-time data stream (both pre-preprocessed using table->retract stream conversion). want generate aggregations , views dynamically on union stream based on query parameters @ run-time - these views use overlapping subsets of data union stream.

it seems it's not possible emit subsets of pre-loaded data further processing downstream operators. possible in flink?

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
