Duo Zhang commented on HBASE-15296: ----------------------------------- Any updates on backporting to branch-1 here? The backporting of HBASE-17914 will be much easier if we could have this patch in branch-1. Thanks. > Break out writer and reader from StoreFile > ------------------------------------------ > > Key: HBASE-15296 > URL: https://issues.apache.org/jira/browse/HBASE-15296 > Project: HBase > Issue Type: Improvement > Components: regionserver > Reporter: Appy > Assignee: Appy > Fix For: 2.0.0 > > Attachments: HBASE-15296-branch-1.1.patch, > HBASE-15296-branch-1.2.patch, HBASE-15296-branch-1.patch, > HBASE-15296-branch-1.patch, HBASE-15296-branch-1-v1.patch, > HBASE-15296-master.patch, HBASE-15296-master-v2.patch, > HBASE-15296-master-v3.patch, HBASE-15296-master-v4.patch, > HBASE-15296-master-v5.patch > > > StoreFile.java is trending to become a monolithic class, it's ~1800 lines. > Would it make sense to break out reader and writer (~500 lines each) into > separate files. > We are doing so many different things in a single class: comparators, reader, > writer, other stuff; and it hurts readability a lot, to the point that just > reading through a piece of code require scrolling up and down to see which > level (reader/writer/base class level) it belongs to. These small-small > things really don't help while trying to understanding the code. There are > good reasons we don't do these often (affects existing patches, needs to be > done for all branches, etc). But this and a few other classes can really use > a single iteration of refactoring to make things a lot better. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
