Webstream Adapter (WSA)

The Webstream Adapter (WSA) pulls content from a URL into the job as a stream. This engine doesn't change the content, but it makes content available to the next Task in the job.

Notes:

• If you are processing with a cognition engine that accepts streams, you can make it the direct child of the WSA.
• If you are processing with a cognition engine that accepts chunks, put a "SI2 audio/video Chunk creator" between the WSA stream output and the cognition chunk input.
• If you have a file that is more than a few megabytes, you should increase the chunkSize (for example: chunkSize:1000000), since otherwise the stream retrieval could be unnecessarily slow.
• The default chunkSize is around 50KB. With a large (>1GB) file, the download can be five times faster with a 1MB chunk size than the default.
