I don't know if this is required? It is documented through kubectl explain --help, should I document somewhere else too? Example: Describe fields and structure of various resources. This command describes the fields associated with each supported API resource. Fields are identified via a simple...
Example: int a,b,c; In this statement,comma is a separator and tells to the compiler that these (a, b, and c) are three different variables. 2) Comma (,) as an operator Sometimes we assign multiple values to a variable using comma, in that case comma is known as operator. ...
All the operators in the query plan are nested inside subQuery1 that is referenced by DFESubquery. All the operators that are pushed down to the DFE engine have names that start with a DFE prefix. As mentioned above, the whole openCypher query plan is executed by the DFE, so as a ...
The following code provides an example of a nested loop join. BEGIN; CREATE TABLE public.nestedloop_test_1 ( a integer not null, b integer not null ); CALL set_table_property('public.nestedloop_test_1', 'distribution_key', 'a'); CREATE TABLE public.nestedloop_test_2 ( c integer not...
Write the syntax of a while statement and explain with an example. (a) What is an accumulator? (b) Describe how an accumulator works with a loop. How do loops work in a flow chart? 1. To learn how nested for loops work, do a walk-through of...

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...

For example, step 2, a merge join, and step 7, a table access, both fed into step 1. A nested, visual representation of the processing sequence is shown in the next section. The value of the POSITION column for the first row of output indicates the optimizer's estimated cost of ...
