             Summary: Potential Refactoring Estimate
                 Key: CASSANDRA-17726
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17726
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Alvin Tan Jian Jia
         Attachments: Cassandra_4.0.4.csv

*Summary*

I have identified a few classes with refactoring potential along with its estimated time to refactor, specifically BatchlogManager.java. The estimated time is based on historical commits containing refactoring and the complexity of the involved classes. The class was refactored once on Jun 12, 2019 along with other classes in commit 310a48efcfdc0fb77fbd5fd6e734bf17667f617d. Given the duration of the last refactoring, could it be possible to improve this class further? I am probably not qualified and experienced enough to point out the exact code needs to be refactored, given my limited knowledge of the project and codebase.

 

*Urgency*

Low priority. For maintenance of code in the long run.

 

Hi,

I am currently doing some research on Estimating Time Taken for Software Refactoring. Cassandra is one of my case studies being a highly popular project. Would appreciate your kind feedback on the appropriateness of the estimated time to refactor. 

I am specifically looking at potential for refactoring, such as breaking functions that are too long into shorter functions, or to remove code duplication. Would you agree that there could be some modification to the code to make it better in the listed classes? And if so, is the estimated time appropriate to carry out the improvement? I will be grateful for any help you can provide.
 # BatchlogManager.java - 4 hours
 # ImmediateExecutor.java - 3 hours
 # DatabaseDescriptor.java - 3.5 hours

Thank you.
