Spring Data MongoDB: ¿Cómo describir la agregación $ merge con Spring Aggregation?

Código que quiero ejecutar por MongoTemplate :

 { $merge: { into: 'someCollection', on: "_id", whenMatched: 'merge', whenNotMatched: 'discard' } }

No encontré ningún método adecuado que me permita describir la etapa $merge , ¿tiene dudas si Spring Data MongoDB incluso es compatible con esta etapa?

Sí, Spring Data MongoDB tiene soporte para la etapa $merge . Su código puede ser ejecutado por MongoTemplate de la siguiente manera.

 MergeOperation mergeOperation = Aggregation.merge() .intoCollection("someCollection") .on("_id") .whenMatched(MergeOperation.WhenDocumentsMatch.mergeDocuments()) .whenNotMatched(MergeOperation.WhenDocumentsDontMatch.discardDocument()) .build();

Utilice esta mergeOperation con mongoTemplate .
