-----------------------------------
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.
