[teiid-issues] [JBoss JIRA] (TEIID-2992) MongoDB: Offset clause causes MongoDB to crash

MongoDB: Offset clause causes MongoDB to crash ---------------------------------------------- Key: TEIID-2992 URL: https://issues.jboss.org/browse/TEIID-2992 Project: Teiid Issue Type: Bug Security Level: Public(Everyone can see) Components: Misc. Connectors Affects Versions: 8.4.1 Environment: MongoDB < 2.5.2 Reporter: Filip Elias Assignee: Ramesh Reddy Labels: Beta1 Fix For: 8.7.1, 8.8 MongoDB(version < 2.5.2) will crash when offset clause is used in SQL query. Althought the bug[1] is in MongoDB (Adding big number into $limit causes Mongodb to shutdown), it is also caused by teiid because it adds max integer into $limit which seems to be unnecessary. Sample query: {code} SELECT INTKEY FROM bqt1.smalla ORDER BY INTKEY OFFSET 45 ROWS {code} Generated mongo command: {code} { aggregate: "smalla", pipeline: [ { $project: { c_0: "$INTKEY" } }, { $sort: { c_0: 1 } }, { $skip: 45 }, { $limit: 2147483647 } ] } {code} [1] https://jira.mongodb.org/browse/SERVER-10136
