--
-- Creates an export task so that you can efficiently export data from a
-- log group to an Amazon S3 bucket. When you perform a @CreateExportTask@
-- operation, you must use credentials that have permission to write to the
-- S3 bucket that you specify as the destination.
--
-- Exporting log data to S3 buckets that are encrypted by KMS is supported.
-- Exporting log data to Amazon S3 buckets that have S3 Object Lock enabled
-- with a retention period is also supported.
--
-- Exporting to S3 buckets that are encrypted with AES-256 is supported.
--
-- This is an asynchronous call. If all the required information is
-- provided, this operation initiates an export task and responds with the
-- ID of the task. After the task has started, you can use
-- <https://docs.aws.amazon.com/AmazonCloudWatchLogs/latest/APIReference/API_DescribeExportTasks.html DescribeExportTasks>
-- to get the status of the export task. Each account can only have one
-- active (@RUNNING@ or @PENDING@) export task at a time. To cancel an
-- export task, use
-- <https://docs.aws.amazon.com/AmazonCloudWatchLogs/latest/APIReference/API_CancelExportTask.html CancelExportTask>.
--
-- You can export logs from multiple log groups or multiple time ranges to
-- the same S3 bucket. To separate log data for each export task, specify a
-- prefix to be used as the Amazon S3 key prefix for all exported objects.
--
-- Time-based sorting on chunks of log data inside an exported file is not
-- guaranteed. You can sort the exported log field data by using Linux
-- utilities.
