   > Support for FilterPushDown, ProjectPushDown, and LimitPushDown to optimize query performance. Have these functions been implemented? I don't seem to have seen this part of the code
   
   Hello, I am very happy to read your comments. Currently this PR belongs to draft status. For the three push-downs you mentioned. As shown in FLIP-127, I am going to implement related implementations of FilterPushDown, ProjectPushDown, and LimitPushDown and optimize es query expressions. Currently only the ProjectPushDown interface is implemented, please refer to Elasticsearch7DynamicSource#applyProjection
