wuyunfeng opened a new issue #3306: [Doris On ES] 2020 roadmap URL: https://github.com/apache/incubator-doris/issues/3306 - 1. 过滤条件转换从BE 上推至 FE,BE只负责扫描数据,FE处理过滤条件 将查询层 和 执行层完全分离,这样很多需求都可以直接在FE中更方便处理了,另外降低社区用户开发成本 - 2. 增加对CastExpr过滤条件的处理 例: k 是float类型,如果 k > 2.0 这时候Doris On ES就没办法下推这个过滤条件了 - 3. 对分词类型的字段增加 `QueryStringQuery`, 将逐步废弃`es_query` - 4. 为FE查询引擎提供更多的ES 外表统计信息,在多表join的时候能够更好的规划 - 5. 增加对 `object` 和 `nested` 字段类型的过滤以及扫描
