[jira] [Created] (HUDI-2299) The log format DELETE block lose the info orderingVal

Danny Chen created HUDI-2299:
--------------------------------

             Summary: The log format DELETE block lose the info orderingVal
                 Key: HUDI-2299
                 URL: https://issues.apache.org/jira/browse/HUDI-2299
             Project: Apache Hudi
          Issue Type: Bug
          Components: Common Core
            Reporter: Danny Chen
             Fix For: 0.9.0


The append handle now always write data block first then delete block, and the delete block only keeps the hoodie keys, when reading, the scanner just read the DELETE block without any info of ordering value, thus, if the we write two records:

insert: {id: 0, ts: 2}
delete: {id: 0, ts: 1}

Finally the insert message is deleted !!!, this is a critical bug for streaming write, we should fix it as soon as possible
