batch

@Nonnull
public static MongoSourceBuilder.Batch<org.bson.Document> batch(@Nonnull
                                                                         String name,
                                                                         @Nonnull

Returns a builder object that offers a step-by-step fluent API to build a custom MongoDB BatchSource for the Pipeline API.

Here's an example that builds a simple source which queries all the documents in a collection and emits the items as a string by transforming each item to json.

Parameters:

name - a descriptive name for the source (diagnostic purposes)

clientSupplier - a function that creates MongoDB client

batch

@Nonnull
public static MongoSourceBuilder.Batch<org.bson.Document> batch(@Nonnull
                                                                         String name,
                                                                         @Nonnull
                                                                         DataLinkRef dataLinkRef)

Returns a builder object that offers a step-by-step fluent API to build a custom MongoDB BatchSource for the Pipeline API.

Here's an example that builds a simple source which queries all the documents in a collection and emits the items as a string by transforming each item to json.

Parameters:

name - a descriptive name for the source (diagnostic purposes)

dataLinkRef - a link to some mongo data link

stream

@Nonnull
public static MongoSourceBuilder.Stream<org.bson.Document> stream(@Nonnull
                                                                           String name,
                                                                           @Nonnull
                                                                           SupplierEx<? extends com.mongodb.client.MongoClient> clientSupplier)

Returns a builder object that offers a step-by-step fluent API to build a custom MongoDB StreamSource for the Pipeline API.

The created source will not be distributed, a single processor instance will be created on an arbitrary member. The source provides native timestamps using ChangeStreamDocument.getClusterTime() and fault tolerance using ChangeStreamDocument.getResumeToken().

Parameters:

name - a descriptive name for the source (diagnostic purposes)

clientSupplier - a function that creates MongoDB client

stream

@Nonnull
public static MongoSourceBuilder.Stream<org.bson.Document> stream(@Nonnull
                                                                           String name,
                                                                           @Nonnull
                                                                           DataLinkRef dataLinkRef)

Returns a builder object that offers a step-by-step fluent API to build a custom MongoDB StreamSource for the Pipeline API.

The source provides native timestamps using ChangeStreamDocument.getWallTime() and fault tolerance using ChangeStreamDocument.getResumeToken().

Parameters:

name - a descriptive name for the source (diagnostic purposes)

dataLinkRef - a link to some mongo data link
