Java: Async MongoTemplate / MongoOperation

Is there a way to insert something asynchronously into mongodb?

I know that mongodb is fairly quick in most cases, but thought maybe I can save some milliseconds by returning as soon as the command is given.

It is for those use cases where you connect to the server to send mongodb a command to insert something. You want to return back to the client once the command is issued and not necessarily wait for a response from mongodb.

I read the documentation: http://docs.spring.io/spring-data/mongodb/docs/current/reference/html/

It only seems to read asynchronously, not insert asychronously.

The Spring Data MongoDB documentation only shows example of using the @Async annotation on query methods, but it is possible to use it on every method.

Quoting this documentation:

Repository queries can be executed asynchronously using Spring’s asynchronous method execution capability. This means the method will return immediately upon invocation and the actual query execution will occur in a task that has been submitted to a Spring TaskExecutor.

Asynchronous invocation of methods is not a Spring Data concern but a Spring Core concern so you can refer to Spring framework documentation.

Simply said, you just need to add the @Async annotation on the method you want and configure a proper task executor in Spring configuration. A sample XML configuration would be:

<task:annotation-driven executor="myExecutor" />
<task:executor id="myExecutor" pool-size="5"/>
