 * <p>Downloads all or a portion of the specified log file, up to 1 MB in size.</p> <p>This command doesn't apply to RDS Custom.</p> <note> <p>This operation uses resources on database instances. Because of this, we recommend publishing database logs to CloudWatch and then using the GetLogEvents operation.
