Subject Fetching operator name from operator context
Date Tue, 26 Jul 2016 18:52:09 GMT
Hi All,

For some utilities, for eg. WindowDataManager, we need to partition disk space under an application
based on the operator name because there can be multiple logical operators in application
using that utility.
Currently the user needs to explicitly set the relative path of each window data manager in
the DAG. However, this can be made easier for the user if the WindowDataManager does this
automatically using the operator name.

In order to retrieve the Operator name from Operator Context there are 2 ways:
1. Add getOperatorName() method to OperatorContext interface

2. Add a name attribute to OperatorContext: IMO this is confusing because attribute suggests
that the name can be set/changed using configuration files but Operator name as of now cannot
be changed or set using config. However, Pramod mentioned there are some other read-only attributes.
The discussion is captured in the Jira below.
<https://issues.apache.org/jira/browse/APEXCORE-448>

I am +1 for option 1.


Please let me know what you think.


Thanks,

Chandni
