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...
CHAPTER-31.What are the different control statements available in java?2.Define vector? Explain the concept of vector with help of an Example?3.Define array. How multidimensional arrays are handled in java? Illustrate the answer.4.What are operators and what are the various types of operators ...
Data in PLAN_TABLE is in a session-level lifecycle. Sessions are isolated from users, and therefore users can only view the data of the current session and current user. PLAN_TABLE cannot be joined with GDS foreign tables. For a query that cannot be pushed down, only such information as ...
Execution information of operators In addition to the basic time and loop execution information, execution info also contains operator-specific execution information, which mainly includes the time consumed for the operator to send RPC requests and the duration of other steps. Poin...
C is one of the most widely used computer programming languages. The reason C is so popular is because it is reliable, simple and easy to use. It is a powerful general-purpose programming language. It can be used to develop software like operating systems, databases, compilers, and so on...
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 order of the operators and their implementations is decided by the query optimizer using a combination of query transformations and physical optimization techniques. While the display is commonly shown in a tabular format, the plan is in fact tree-shaped. For example, consider the following ...
In much the same way, computing aficionados draw a distinction between different types of cloud. Public clouds are provided by people such as Amazon, Google, and IBM: in theory, all users share space and time on the same cloud and access it the same way. Many companies, for example, use...
Abstraction can be of two types, namely, data abstraction and control abstraction. Data abstraction means hiding the details about the data and control abstraction means hiding the implementation details. In object-oriented approach, one can abstract both data and functions. However, generally, the ...
To develop software, the object-oriented concepts need to be implemented in any high-level language. The high-level language that implements the concepts of object-oriented programming is known as an object-oriented language (also called an OO language). In general, an object-oriented language mu...
