Subject [jira] [Updated] (HIVE-6060) Define API for RecordUpdater and UpdateReader
Date Fri, 20 Dec 2013 00:33:08 GMT

     [ https://issues.apache.org/jira/browse/HIVE-6060?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Owen O'Malley updated HIVE-6060:
--------------------------------

    Attachment: h-5317.patch

Rowids are not unique across buckets and thus the unique identifier is thus: (transaction
id, bucket id, row id). Alan suggested offline that I add bucket id to API so that we aren't
forced to maintain the current restriction of one HDFS file per a bucket. I've also added
my thoughts on what the reader would look like.

I also need to look at what the API looks like for vectorization.

> We need to define some new APIs for how Hive interacts with the file formats since it
needs to be much richer than the current RecordReader and RecordWriter.
