// Uploads a batch of log events to the specified log stream. You must include the
// sequence token obtained from the response of the previous call. An upload in a
// newly created log stream does not require a sequence token. You can also get the
// sequence token in the expectedSequenceToken field from
// InvalidSequenceTokenException. If you call PutLogEvents twice within a narrow
// time period using the same value for sequenceToken, both calls might be
// successful or one might be rejected. The batch of events must satisfy the
// following constraints:
//
// * The maximum batch size is 1,048,576 bytes. This size
// is calculated as the sum of all event messages in UTF-8, plus 26 bytes for each
// log event.
//
// * None of the log events in the batch can be more than 2 hours in
// the future.
//
// * None of the log events in the batch can be older than 14 days or
// older than the retention period of the log group.
//
// * The log events in the batch
// must be in chronological order by their timestamp. The timestamp is the time the
// event occurred, expressed as the number of milliseconds after Jan 1, 1970
// 00:00:00 UTC. (In Amazon Web Services Tools for PowerShell and the Amazon Web
// Services SDK for .NET, the timestamp is specified in .NET format:
// yyyy-mm-ddThh:mm:ss. For example, 2017-09-15T13:45:30.)
//
// * A batch of log events
// in a single request cannot span more than 24 hours. Otherwise, the operation
// fails.
//
// * The maximum number of log events in a batch is 10,000.
//
// * There is a
// quota of 5 requests per second per log stream. Additional requests are
// throttled. This quota can't be changed.
//
// If a call to PutLogEvents returns
// "UnrecognizedClientException" the most likely cause is an invalid Amazon Web
// Services access key ID or secret key.
