Creating an Inventory Job
Feature description
This API is used to create an inventory job for a bucket. For more information, see Inventory Overview.
Note：
Up to 1,000 inventory jobs can be created in one COS bucket.
You must write a bucket policy for the destination bucket in order for COS to put the resulting file of the inventory job into the destination bucket.
To call this API, make sure that you have the necessary permission for bucket inventory jobs; the bucket owner has permission by default. If you do not have such permission, you can request permission from the bucket owner.
Request samples
Sample 1. Creating an inventory job with server-side encryption.
cos.putBucketInventory({
    Bucket: 'sourcebucket-1250000000',  /* Required */
    Region: 'ap-beijing',                                  /* Required */
    Id: 'inventory_test',               /* Required */
    InventoryConfiguration: {
        Id: 'inventory_test',
        IsEnabled: 'true',
        Destination: {
            COSBucketDestination: {
                Format: 'CSV',
                AccountId: '100000000001',
                Bucket: 'qcs::cos:ap-beijing::targetbucket-1250000000',
                Prefix: 'inventory_test_prefix',
                Encryption: {
                    SSECOS: ''
                }
            }
        },
        Schedule: {
            Frequency: 'Daily'

            'ETag'
        ]
    }
}, function(err, data) {
    console.log(err || data);
});
Sample 2. Creating an inventory job without server-side encryption.

                AccountId: '100000000001',
                Bucket: 'qcs::cos:ap-beijing::targetbucket-1250000000',
                Prefix: 'inventory_test_prefix'
            }

            Frequency: 'Daily'
        },
        Filter: {
            Prefix: 'filter_prefix'
