Subject [jira] [Commented] (SQOOP-1744) TO-side: Write data to HBase
Date Tue, 02 Dec 2014 23:27:13 GMT

    [ https://issues.apache.org/jira/browse/SQOOP-1744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14232297#comment-14232297

Ryan Blue commented on SQOOP-1744:
----------------------------------

You're right that HBase doesn't buy us much. In that situation, where we can't isolate a subset
of the data that might change, I think we have two options: either rewrite the entire dataset
each time or maintain the dataset in HBase. We shouldn't overlook the second option, which
would facilitate the fetch frequency that you want. Parquet is a great format to use, but
if we have to constantly rewrite the entire dataset or very substantial portions of it, then
it might not be worth the storage savings.

> Propose to write data into HBase. Note that different to HDFS, HBase is append only.
Merge does not work for HBase.
