问题 I'm having performance issues when querying ~12,000 user documents, indexed by 1 column, (companyId), no other filter. The whole collection only has ~27000. It took me about 12 seconds to get the ~12000 rows of data... I tried running explain for this query: db.instoreMember.find({companyId:"5b6be3e2096abd567974f924"}).explain(); result follows: { "queryPlanner" : { "plannerVersion" : 1, "namespace" : "production.instoreMember", "indexFilterSet" : false, "parsedQuery" : { "companyId" : { "$eq

I use MongoRepository to store this value: @Repository public interface AuditTableRepo extends MongoRepository<AuditTable, String> { } Now when I store it in the Collection it looks like this: whereas I want it to look like this: "

问题 I am using Spring Boot and Spring Data MongoDB to interface with an underlying sharded MongoDB cluster. My Spring Boot Application access the cluster via a mongos router. Using Spring Data MongoDB, you can specify the collection an object is persisted to via @Document(collection = "nameOfCollection") , or it defaults to the class name (first letter lowercase). These collections do not need to exist before-hand; they can be created at runtime. To shard a collection in MongoDB, you need to 1 -

问题 Is there a way to find the query that was run against the database in spring data mongodb? I know this is possible in case of JPA. So was just wondering if there was something similar in Spring data MongoDB? 回答1: The easiest way is to set the log level to DEBUG for org.springframework.data.mongodb . 回答2: logging: level: org.springframework.data.mongodb.core.MongoTemplate: DEBUG To clarify Oliver's answer add that to the application.yml file or properties file. 来源： https://stackoverflow.com
