使用“Container.GetItemLinqQueryable”和“Container.GetItemQueryIterator”有什么区别？

Question

I was wondering what was the difference (performance or something else) between using either of these methods to query a cosmo container, other than using LINQ vs SQL and assuming that I use the ToFeedIterator() method like mentioned in the docs (also below in case it changes) for Container.GetItemLinqQueryable .

// LINQ query generation
using (FeedIterator<Book> setIterator = container.GetItemLinqQueryable<Book>()
                     .Where(b => b.Title == "War and Peace")
                     .ToFeedIterator())
{                   
    //Asynchronous query execution
    while (setIterator.HasMoreResults)
    {
        foreach(var item in await setIterator.ReadNextAsync())
        {
            Console.WriteLine(item.Price); 
        }
    }
}

Answer 1

Container.GetItemLinqQueryable -
This method creates a LINQ query for items in an Azure Cosmos DB service under a container. For asynchronous execution with FeedIterator, utilise the IQueryable extension function ToFeedIterator().

Container.GetItemQueryIterator -
Using a SQL statement, this method creates a query for items under a container in an Azure Cosmos database. It returns a FeedIterator.
