Spring Data-MongoDb Options for aggregation method

How can i set "allowDiskUse" option in aggregation method in spring data-mongodb framework ?

Solution

  • The core aggregation abstraction in Spring Data MongoDB is - as the name suggests - Aggregation. It exposes a fluent API to build up a pipeline using aggregation operations.

    As of version 1.6.0.M1 the Aggregation class has a ….withOptions(…) method to be used like this:

    Aggregation aggregation = newAggregation(…) // build up pipeline in here
  .withOptions(newAggregationOptions().allowDiskUse(true).build());
