A single product document cannot exceed 32MB (this EXCLUDES binary data such as images or videos). For comparison, the entire King James Bible is 9MB uncompressed. There are no limitations apart from this. You can define as many schemas as required and each schema can have any number of attributes. File sizes for imports via feeds are effectively unlimited. Ad hoc imports via the browser are chunked but limitations may exist in the browser that prevent upload of very large files. We recommend the use of pre-defined feeds for very large files. The DAM module of Pimberly for the storage or images, videos and other product related files is backed by Amazon S3 storage. This has a theoretical maximum file size of 5 Terabytes.
