Attila Szabo created SQOOP-2983: ----------------------------------- Summary: OraOop export has degraded performance with wide tables Key: SQOOP-2983 URL: https://issues.apache.org/jira/browse/SQOOP-2983 Project: Sqoop Issue Type: Bug Reporter: Attila Szabo Assignee: Attila Szabo Priority: Critical
The current version of OraOOP seems to perform very low from performance POV when --direct mode turned on (regardless if the partitioned feature is turned of). Just as a baseline from the current trunk version: Inserting 100.000 rows into a 800 column wide Oracle table has 400-600 kb/sec with direct mode on my cluster, while the standard oracle driver can produce up to 1.2-1.8 mb/sec. (depending on the number of mappers, batch size). Inserting 1.000.000 rows into the same table goes up to 800k-1mb/sec with OraOOP, however with the standard Oracle connector it's around 3.5mb/sec. It seems OraOOP export needs a thorough review and some fixing. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
