MongoTemplate.count Specify strategy #4727

Closed dv2018f closed 1 week ago

dv2018f commented 3 weeks ago

Upon reviewing the source code, it was found that MongoTemplate executes the count method. The underlying default is AGGREGATE. Can we specify it as the COMMAND policy, as aggregate takes longer to scan public long countDocuments(Bson filter, CountOptions options) { return this.executeCount((ClientSession)null, filter, options, CountStrategy.AGGREGATE); }

I'm not entirely sure I understand what you want to achieve given MongoOperations has dedicated methods like estimatedCount to operate upon collection statistics. Additionally you could call MongoTemplate#useEstimatedCount(...) to apply a different count strategy.

Further more the snippet from the description refers to the MongoDB client API of MongoCollectionImpl which is maintained by the java drivers team at MongoDB. Please report issues/enhancements with them here.
