Workflow Orchestration


Workflow Orchestration is the end-to-end management of people, digital workers, systems, and data in a process.
Workflow orchestration is the process of managing and coordinating tasks, systems, and processes to achieve a specific goal.
Workflow orchestration involves designing, executing, and optimizing workflows to ensure that all elements work together smoothly.

Netflix Conductor Workflow Implementation

Conductor allows you to build a complex application using simple and granular tasks.
Conductor keeps track of the state, calls tasks in the right order (sequentially or in parallel, as defined), retry calls if needed, handle failure scenarios gracefully, and outputs the final result.

Workflows
Workflow Definition
Workflow Definitions are like OOP classes
A Workflow Definition contains a collection of Task Configurations. 
This is the blueprint which specifies the order of execution of tasks within a workflow. 
This blueprint also specifies how data/state is passed from one task to another (using task input/output parameters).
Additionally, the Workflow Definition contains metadata regulating the runtime behavior workflow, such what input and output parameters are expected for the entire workflow, and the workflow's the timeout and retry settings.


Workflow Execution
Workflows Executions are like object instances.
Each time a Workflow Definition is invoked with a given input, a new Workflow Execution with a unique ID is created.
Definitions to Executions have a 1:N relationship.

PL/SQL

PL/SQL PL/SQL stands for Procedural Language extensions to the Structured Query Language (SQL). PL/SQL can execute a number of queries in one block using single command. One can create a PL/SQL unit such as procedures, functions, packages, triggers, and types, which are stored in the database for reuse by applications. The PL/SQL engine resides in the Oracle engine. The Oracle engine can process not only single SQL statement but also block of many statements. Structure of PL/SQL Block: DECLARE     declaration statements; BEGIN     executable statements EXCEPTIONS     exception handling statements END; / Example : SET SERVEROUTPUT ON; SQL> DECLARE        var varchar2(40) := 'I love GeeksForGeeks' ;      BEGIN        dbms_output.put_line(var);      END;      / PL/SQL Functions PL/SQL functions are reusable blocks of code that can be used to perform specific tasks. They are...

JAVA8 Features

Java8 Features 1) Lambda Expressions : Concise functional code using ->. Lambda Expression basically expresses an instance of the functional interface, Lambda Expression provides a clear and concise way to represent a method of the functional interface using an expression. 2) Functional Interfaces : Single-method interfaces. An interface that contains only one abstract method is known as a functional interface. There is no restriction, that can have n number of default and static methods inside a functional interface. A functional interface is an interface that contains only one abstract method.  @FunctionalInterface annotation is used to ensure that the functional interface can’t have more than one abstract method. Runnable, ActionListener, and Comparable are some of the examples of functional interfaces.   Runnable –> This interface only contains the run() method.   Comparable –> This interface only contains the compareTo() method.   ActionListener –> ...

Build Automation

-
ANT: Ant was the first build tool released in 2000. Ant was developed on procedural programming idea. Ant was improved with an ability to accept plug-ins and dependency management over the network, with the help on Apache-IVY. Drawbacks: 1) XML is used as a format to write the build scripts. 2) Being hierarchical is not good for procedural programming, and 3) XML is relatively unmanageable.   MAVEN: Maven was introduced in 2004. Maven relied on the conventions and was able to download the dependencies over the network. Benefits : Life cycle of Maven, while following the same life cycle for multiple projects continuously. Problems: 1) Maven does not handle the conflicts between versions of the same library. 2) Complex customised build scripts are difficult to write in Maven, as compared to writing the build scripts in ANT. GRADLE : Gradle came into picture in 2012 Features  Declarative builds and build-by-convention 1) Gradle is available with separate Domain Specific Language ...
