The SubmitFeed operation uploads a file and
any necessary metadata for processing. Note that you must calculate a
Content-MD5 value for the submitted file. For more information about creating a
Content-MD5 value, see Using the Content-MD5 hash with the SubmitFeed and GetFeedSubmissionResult operations.
Feed size is limited to 2 GB (231-1, or 2,147,483,647 bytes) per feed.
If you have a large amount of data to submit, you should submit feeds smaller
than the feed size limit by breaking up the data, or submit the feeds over a
period of time. For optimal performance, a good practice is to submit feeds with
a size limit of 30,000 records/items, or submit feeds over a period of time,
such as every few hours.
This operation is available in all marketplaces.

explanation of throttling, see Throttling: Limits to how often you can submit requests in the Amazon MWS Developer Guide.

Maximizing feed performance
You can generally get the best overall feed processing performance by
following these guidelines:
- Avoid submitting a lot of feeds with only a few records in each feed.
When possible, combine the data into less frequent larger feeds.
- Include only the products you are updating, not your entire inventory.
- Upload one feed of the same type no more than once every 20 minutes.
Allow more time between larger feeds.
- Keep file size below 10 MB
Setting the Content-Type for a feed
Your feeds must be in a valid encoding based on your marketplace and file
type, and that encoding must be specified as an HTTP Content-Type header.
The following table shows the HTTP Content-Type header you should use for
flat files and XML files for each marketplace:

|North America and Europe
Submitting Feeds with Multiple Marketplace IDs
If an Amazon seller is registered in multiple marketplaces, then the seller
has multiple marketplace IDs associated with their merchant/seller ID. For more information on submitting a feed using
multiple marketplace IDs, see Using Multiple Marketplaces.
