Answer: Change the partition key from facility ID to a randomly generated key.
Option A is CORRECT because changing the partition key from facility ID to a randomly generated key will help distribute the data more evenly across the shards. This approach helps avoid hot shards that are caused by the uneven distribution of facility IDs, leading to more balanced write throughput across all shards.
