A banking application processes thousands of transactions each second. Each transaction payload must have end-to-end encryption. The application encrypts each transaction locally by using the AWS Key Management Service (AWS KMS) GenerateDataKey operation. A developer is testing the application and receives a ThrottlingException error.
Which actions are best practices to resolve this error? (Choose two.)

A. Use the LocalCryptoMatenalsCache feature of the AWS Encryption SDK encryption library.
B. Call the AWS KMS Encrypt operation directly to allow AWS KMS to encrypt the data.
C. Create a case in the AWS Support Center to increase the quota for the account.
D. Use Amazon Simple Queue Service (Amazon SQS) to queue the requests to AWS KMS.
E. Switch to an AWS KMS custom key store.
