org.apache.flink.connector.mongodb.sink

Class MongoSink<IN>

java.lang.Object

org.apache.flink.connector.mongodb.sink.MongoSink<IN>

Type Parameters:

IN - Type of the elements handled by this sink

All Implemented Interfaces:

Serializable, org.apache.flink.api.connector.sink2.Sink<IN>

@PublicEvolving
public class MongoSink<IN>
extends Object
implements org.apache.flink.api.connector.sink2.Sink<IN>

Mongo sink converts each incoming element into MongoDB WriteModel (bulk write action) and bulk writes to mongodb when the number of actions is greater than batchSize or the flush interval is greater than batchIntervalMs.

The following example shows how to create a MongoSink sending records of Document type.

 MongoSink<Document> sink = MongoSink.<Document>builder()
     .setUri("mongodb://user:password@127.0.0.1:27017")
     .setDatabase("db")
     .setCollection("coll")
     .setBatchSize(5)
     .setSerializationSchema(
         (doc, context) -> new InsertOneModel<>(doc.toBsonDocument()))
     .build();
