[teiid-issues] [JBoss JIRA] (TEIID-2027) maxSourceRows being incorrectly applied when query returns less rows than the limit

Graeme Gillies created TEIID-2027: ------------------------------------- Summary: maxSourceRows being incorrectly applied when query returns less rows than the limit Key: TEIID-2027 URL: https://issues.jboss.org/browse/TEIID-2027 Project: Teiid Issue Type: Bug Affects Versions: 7.6 Environment: Teiid 7.6 running on JBoss EAP 5.1 on RHEL 5. JDK is java version "1.6.0_22" OpenJDK Runtime Environment (IcedTea6 1.10.6) (rhel-1.25.1.10.6.el5_8-x86_64) OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode) Reporter: Graeme Gillies Assignee: Steven Hawkins We have a user who is trying to run a particularly large query against our VDB but is getting the error {code} {code} Which seems fairly self explanatory, as we do have maxSourceRows set to 100000 in teiid-jboss-beans.xml. Unfortunately though, the query in question should be returning only about 2000 rows, so it shouldn't be hitting this error at all. In fact, I am able to replicate this problem with the following simple script {noformat} #!/usr/bin/env python import psycopg2 conn = psycopg2.connect("host=vdb.example.com port=35432 dbname=MyVDB user=user password=password") cursor = conn.cursor() query = "SELECT bugs.bug_id, bugs.creation_ts FROM Bugzilla.bugs WHERE bugs.bug_id IN (%s)" % ','.join(map(str, range(1,1002))) cursor.execute(query) rows = cursor.fetchall() cols = [t[0] for t in cursor.description] for row in rows: print ", ".join(["%s = %s" % (col, value) for col, value in zip(cols, row)]) conn.close() {noformat} If I change {code} query = "SELECT bugs.bug_id, bugs.creation_ts FROM Bugzilla.bugs WHERE bugs.bug_id IN (%s)" % ','.join(map(str, range(1,1002))) {code} to {code} query = "SELECT bugs.bug_id, bugs.creation_ts FROM Bugzilla.bugs WHERE bugs.bug_id IN (%s)" % ','.join(map(str, range(1,1001))) {code} The code works fine, so it seems that there is some 1000 row limit somewhere that Is being used instead of the value we set (100000) -- This message is automatically generated by JIRA.
