A gaming company stores player profiles in Azure Cosmos DB for NoSQL. The container has a partition key of `playerId`. The application frequently queries for a player's profile by `playerId` and also runs a query to find all players in a given country. The team notices that the query for players by country consumes a high number of Request Units (RUs). They want to reduce RU consumption for this query. Which approach should they take?

Create a second container with `country` as the partition key and synchronize data using the change feed.

Change the partition key to `country`.

Add a composite index on `country` and `playerId`.

Use a cross-partition query with a larger page size.

What is the primary purpose of the change feed in Azure Cosmos DB?

To provide a log of inserts and updates to items in a container

To replicate data to another region automatically

To enable real-time analytics on query performance

To store backups of the container data

What is a common way to store embeddings in Azure Cosmos DB for NoSQL to support semantic retrieval?

As a base64-encoded string in a separate container

As a JSON string in a property named 'embedding'

As a binary large object (BLOB) in Azure Blob Storage

As an array of floating-point numbers in a property of the JSON item
