Kurt Young reassigned FLINK-5524: --------------------------------- Assignee: Kurt Young > Support early out for code generated conjunctive conditions > ----------------------------------------------------------- > > Key: FLINK-5524 > URL: https://issues.apache.org/jira/browse/FLINK-5524 > Project: Flink > Issue Type: Improvement > Components: Table API & SQL > Affects Versions: 1.2.0, 1.1.4, 1.3.0 > Reporter: Fabian Hueske > Assignee: Kurt Young > > Currently, all nested conditions for a conjunctive predicate are evaluated > before the conjunction is checked. > A condition like {{(v1 == v2) && (v3 < 5)}} would be compiled into > {code} > boolean res1; > if (v1 == v2) { > res1 = true; > } else { > res1 = false; > } > boolean res2; > if (v3 < 5) { > res2 = true; > } else { > res2 = false; > } > boolean res3; > if (res1 && res2) { > res3 = true; > } else { > res3 = false; > } > if (res3) { > // emit something > } > {code} > It would be better to leave the generated code as early as possible, e.g., > with a {{return}} instead of {{res1 = false}}. The code generator needs a bit > of context information for that. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
