 Segment uses the `messageId` or the `userId || anonymousId` as the `PartitionKey`. The partition key is used by Amazon Kinesis to distribute data across shards. Amazon Kinesis segregates the data records that belong to a stream into multiple shards, using the partition key associated with each data record to determine which shard a given data record belongs to.

+The following best practices help you implement additional Amazon Kinesis functionality like encryption, the use of multiple data sources, and more efficient data transmission. 
 
 ### Updating IAM role permissions for encryption
 Extra permissions need to be added to the IAM role if using at-rest encryption on the Kinesis stream. An updated role policy like below resolves issues when submitting PutRecords into Kinesis stream using encryption:
