■ Collection 클래스의 index_information 메소드를 사용해 인덱스 정보를 구하는 방법을 보여준다.

▶ 예제 코드 (PY)


from pymongo import MongoClient, ASCENDING

databaseURL = "mongodb://localhost:27017/"

mongoClient = MongoClient(databaseURL)

testDatabase = mongoClient["testdb"]

userCollection = testDatabase["user"]

userCollection.delete_many({})

userList = []

for i in range(1, 6):
    user = {
        "email"    : f"user{i}@sample.com",
        "password" : f"password{i}"
    }

    userList.append(user)

userCollection.insert_many(userList)

indexName = testDatabase.userCollection.create_index([("email", ASCENDING)], unique = True)

indexInformationDictionary = testDatabase.userCollection.index_information()

print(indexInformationDictionary)
