AWS Kinesis is a platform on AWS to collect, process, and analyze real-time, streaming data. It allows developers to build applications that can continuously ingest and process large streams of data records in real-time. Kinesis is commonly used for log and event data collection, real-time analytics, and more.
When using AWS Kinesis, you might encounter the error code KMSOptInRequired. This error typically appears when you attempt to use AWS Key Management Service (KMS) for encrypting data streams but your AWS account is not configured to use KMS.
The KMSOptInRequired error indicates that your AWS account has not been opted in to use the AWS Key Management Service (KMS). KMS is a managed service that makes it easy to create and control the encryption keys used to encrypt your data. If your account is not opted in, any attempt to use KMS with AWS services like Kinesis will result in this error.
This issue arises because AWS KMS is not automatically enabled for all AWS accounts. Some regions or accounts may require explicit opt-in to use KMS, especially if the account was created before KMS was available in that region.
To resolve this issue, you need to enable KMS for your AWS account. Follow these steps:
Go to the AWS Management Console and sign in with your AWS account credentials.
In the AWS Management Console, search for KMS in the services search bar and select Key Management Service from the results.
If your account is not opted in, you will see an option to enable KMS. Follow the on-screen instructions to opt-in. This may involve accepting terms and conditions or enabling the service in specific regions.
Once you have opted in, verify that KMS is enabled by attempting to create a new key or by checking the status of existing keys. You can also use the AWS CLI to list keys:
aws kms list-keys
