mihai-cazacu-adswizz opened a new issue #6969: The materialized view returns different results than the base data source URL: https://github.com/apache/incubator-druid/issues/6969 The query that is using the base data source: ``` { "query": { "context": { "useCache": false, "populateCache": false, "timeout": 3600000 }, "dataSource": "the-kafka-data-source", "queryType": "groupBy", "aggregations": [ { "fieldName": "metricASum", "name": "metricASum", "type": "longSum" } ], "dimensions": [ "dimA" ], "granularity": "all", "intervals": [ "2019-01-30T00:01Z/2019-01-31T23:59Z" ], "limitSpec": { "limit": 1, "type": "default" } }, "queryType": "view" } ``` and its result: ``` [ { "version": "v1", "timestamp": "2019-01-30T00:01:00.000Z", "event": { "client": "dimA", "metricASum": 4342 } } ] ``` And the one that uses the view (the same query, only the `dataSource` is changed): ``` { "query": { "context": { "useCache": false, "populateCache": false, "timeout": 3600000 }, "dataSource": "the-kafka-data-view-source", "queryType": "groupBy", "aggregations": [ { "fieldName": "metricASum", "name": "metricASum", "type": "longSum" } ], "dimensions": [ "dimA" ], "granularity": "all", "intervals": [ "2019-01-30T00:01Z/2019-01-31T23:59Z" ], "limitSpec": { "limit": 1, "type": "default" } }, "queryType": "view" } ``` and its result: ``` [ { "version": "v1", "timestamp": "2019-01-30T00:01:00.000Z", "event": { "client": "dimA", "metricASum": 291 } } ] ``` The spec and the payloads can be found [here](https://github.com/apache/incubator-druid/issues/6945).
