-- Associates the specified KMS key with the specified log group.
--
-- Associating a KMS key with a log group overrides any existing
-- associations between the log group and a KMS key. After a KMS key is
-- associated with a log group, all newly ingested data for the log group
-- is encrypted using the KMS key. This association is stored as long as
-- the data encrypted with the KMS keyis still within CloudWatch Logs. This
-- enables CloudWatch Logs to decrypt this data whenever it is requested.
--
-- CloudWatch Logs supports only symmetric KMS keys. Do not use an
-- associate an asymmetric KMS key with your log group. For more
-- information, see
-- <https://docs.aws.amazon.com/kms/latest/developerguide/symmetric-asymmetric.html Using Symmetric and Asymmetric Keys>.
--
-- It can take up to 5 minutes for this operation to take effect.
--
-- If you attempt to associate a KMS key with a log group but the KMS key
-- does not exist or the KMS key is disabled, you receive an
-- @InvalidParameterException@ error.
