What is the difference between for loops and while loops in c programming? What is the advantage of using a do-while loop over a while loop? What is the difference between for-each loop and for loops in java? What is the difference between i++ an...
Using Loops in Programming In most of the programming languages, three looping structures 'for', 'while', and 'do-while' are used to perform the statements that need to be executed repetitively until a given condition is satisfied. For example, the 'for' loop can be implemented (in C) as...
The implementation of this API operation differs based on types of operators. This API operation is called for multiple times until data of all downstream operators is pulled. The value of this parameter indicates the execution duration in the next phase and is in the format of maximum duration...
Accessing row source 2 is known a probing the inner table For nested loops to be efficient it is important that the first row source returns as few rows as possible as this directly controls the number of probes of the second row source. Also it helps if the access method for row source...
The 'break' and 'continue' expressions also work with the 'while' and 'repeat...until' loops. Return Values A function returns the value and type of the last expression evaluated. Functions will always have a return value, although it may not be meaningful. The 'return' statement can be...

- `BatchGet` RPC request is sent in the `prefetch` step. - `Get` RPC request is sent when the `insert on duplicate` statement executes `duplicate update`. - `backoff`: Contains different types of backoff and the total waiting time of backoff. ### IndexJoin The `IndexJoin` operator...
In cases where there is an alternative plan that performed better than the plan generated by the optimizer, the first step in diagnosing why the Optimizer picked the sub-optimal plan is to visually inspect both of the execution plans. Examining the different aspects of an execution plan, from ...
