| Doc Text: |
MongoDB would crash when an offset clause was used in an SQL query. This was becuase, during translation from query to API language, objects were defaulting the limit at INT_MAX during the translation. To fix this problem, an explicit check was added to the MongoDB query parser to check for INT_MAX and skip setting the value if it matches. As a result, MongoDB will no longer crash when queries with offset clauses are run.

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: SELECT INTKEY FROM bqt1.smalla ORDER BY INTKEY OFFSET 45 ROWS Generated mongo command: { aggregate: "smalla", pipeline: [ { $project: { c_0: "$INTKEY" } }, { $sort: { c_0: 1 } }, { $skip: 45 }, { $limit: 2147483647 } ] } [1] https://jira.mongodb.org/browse/SERVER-10136
