Masatake Iwasaki commented on SQOOP-999:
----------------------------------------
It is preferable to use not psql (outer process) but Copy API of PostgreSQL
JDBC Driver in order to reduce external dependency. I am going to consider its
feasibility.

> Support bulk load from HDFS to PostgreSQL using COPY ... FROM
> -------------------------------------------------------------

> Key: SQOOP-999
> URL: https://issues.apache.org/jira/browse/SQOOP-999
> Project: Sqoop
> Issue Type: New Feature
> Components: connectors/postgresql
> Affects Versions: 1.4.3
> Environment: PostgreSQL
> Reporter: Ruslan Al-Fakikh
>
> Initially taken from here:
> https://issues.cloudera.org/browse/SQOOP-184
> As Cloudera site is no longer used:
> {quote}
> 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.
> {quote}
> 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.
