Variables type use case

_AnonymousUser — Sat, 15 Oct 2016 08:46:13 GMT

Hi,
I can see at least three kind of variables (There might be even more ?):
-Context variables
-Environnement variables (With component tSetEnv)
-Global variables (With component tSetGlobalVar)

Could someone help me to understand use cases of these three kind of variables ?
And especially when context variables cannot be used and one of two others has to be used ?
Eric

not in Your order
Environment - it is OS level variables, such as ORA_HOME, JAVA_HOME and etc. You can for example define OS variable - RUN_ENV - dev or qual or prod, than Your Talend Job will check this variable and use in Job logic
Global variable - most often used way for:
- store value between component
- save value and etc
Context variables - some time could be used as global, but main goal - define context group (like - dev, prod, qual) and anywhere where it possible - use context variable for PATH, name, connection information and etc
then changing only 1 parameter You can run Job with different set of all parameters
also You can store context variables values in csv file and change them for compiled Jobs
