'How to configure maxDegreeOfParallelism for cosmosdb in Springboot?
I want to configure the CosmosQueryRequestOptions.maxDegreeOfParallelism while using the CosmosRepository. I didn't find any documentation around it.
This blog shows how to configure and use this setting through a custom client, but I want to use the repository instead. https://medium.com/@middha.nishant173/improve-query-performance-with-azure-cosmosdb-java-sdk-v4-db1fc54cb484

CosmosQueryRequestOptions is implementation detail for Spring Data Cosmos SDK, so customers cannot set it through spring application.
This can be implemented as a new feature, and can be exposed through application.properties via query.maxDegreeOfParallelism - which customers can opt in if they want.
Default value for maxDegreeOfParallelism is 0, which is the right value for single partition queries. For cross partition queries in the current SDK version, you can get the cosmosClient through spring boot applicationContext and run the query directly against the client. This example shows how to do it - https://github.com/Azure/azure-sdk-for-java/blob/main/sdk/cosmos/azure-spring-data-cosmos-test/src/test/java/com/azure/spring/data/cosmos/repository/integration/PageableAddressRepositoryIT.java#L144
