Wanja Pernath commented on TEIID-1411:
--------------------------------------
To be clear here: The inner select statement for getting accounts is executed exactly once
with the correct behavior.
Unfortunately, the select statement for getting Case information is executed without *any*
condition. This means all millions of Case rows are read and then compared with the
account information on the teiid client side.
Cheers,

Incorrect IN behavior when using a SELECT clause as IN values
-------------------------------------------------------------
Key: TEIID-1411
URL: https://issues.jboss.org/browse/TEIID-1411
Project: Teiid
Issue Type: Bug
Components: Salesforce Connector
Affects Versions: 7.1.1
Environment: Teiid 7.1.1 on EAP 5.1 with CXF enabled
Reporter: Wanja Pernath
Assignee: Steven Hawkins
A query like this:
select CaseNumber
from gss.general.Case
where accountId in (select id from gss.general.Account where name like 'A condition
which should return 1 or more accounts')
results in a Teiid client side calculation of the result set where Teiid is scanning all
Cases first and and filtering out the necessary ones.
Expected is that Teiid would let Salesforce figure out the condition by pushing down the
query:
SELECT id from Account where name like 'A condition which should return 1 or more
accounts';
SELECT CaseNumber from Case where AccountId IN ('id-1', 'id-2',
'id-3'....)
Here's the log detail:
