[jira] [Commented] (SQOOP-999) Support bulk load from HDFS to PostgreSQL using COPY ... FROM

["Qiuzhuang Lian (JIRA)" <ji...@apache.org>]

Qiuzhuang Lian commented on SQOOP-999:
--------------------------------------

With postgres copy delimiter as of ctrl+c like special char of \001, it would break hadoop job.xml syntax since XML 1.0 can not support ctrl+x char in its configurations. We have to encode this delimiter to work around copy.

> Sqoop currently supports bulk export from PostgreSQL but not bulk import. PostgreSQL support COPY <table> FROM <filename> syntax and readily accepts CSV data. We should support this so there is --direct support in both directions.

> A note from myself:
> the pg_bulkupload feature is already implemented:
> https://issues.apache.org/jira/browse/SQOOP-390
> pg_builupload is a third-party tool, I guess supporting COPY would be a better case.
