## Reactive Template API usage with `ReactiveMongoTemplate`
|

|

The main reactive Template API class is `ReactiveMongoTemplate`, ideally used through its interface `ReactiveMongoOperations`. It defines a basic set of reactive data access operations using [Project Reactor](http://projectreactor.io) `Mono` and `Flux` reactive types.

Reactive data access reads and converts individual elements while processing the stream.

## Reactive Repository support
|
||||
|
||||
|
||||
Spring Data MongoDB provides reactive repository support with Project Reactor and RxJava 1 reactive types. The reactive API supports reactive type conversion between reactive types.
