== RxJava 3 API

The Mongo client provides an Rxified version of the original API.

=== Creating an Rxified client

To create an Rxified Mongo client, make sure to import the `link:../../apidocs/io/vertx/rxjava3/ext/mongo/MongoClient.html[MongoClient]` class.
Then use one of the `create` methods to get an instance:

[source,java]

`link:../../apidocs/examples/RxMongoClientExamples.html#createClient-io.vertx.rxjava3.core.Vertx-io.vertx.core.json.JsonObject-[createClient]`

=== Finding documents in batches

A `link:../../apidocs/io/vertx/rxjava3/core/streams/ReadStream.html[ReadStream]` can be converted to a `link:../../apidocs/io/reactivex/rxjava3/core/Flowable.html[Flowable]`, which is handy when you have to deal with large data sets:
