Requests to transform files from external HTTP URLs may incur additional latency due to internal download operations:
Video and audio transformations incur ~1 second of extra latency per 75MB of input file size when using external HTTP URLs.*
Image transformations incur no extra latency: the performance is the same as using Bytescale's Built-in Storage.
*
Applies to the first request only: once the result is cached all subsequent requests to the same URL will return near-instantly.
Bytescale supports two options for processing externally-hosted files:
To process files from a fixed base URL:
Create a folder in the Bytescale Dashboard.
Edit the folder's settings.
Click on "Storage Settings".
Change "Storage Type" to "External HTTP URL".
For "Use a Base URL" select "Yes"
Enter the base URL to fetch files from.
Click on "Save Changes". (Don't forget this step before continuing!)
Try it out:
Copy the "Example CDN URL" from the UI.
Replace "example.jpg" with a relative path you want to fetch from the underlying URL.
To process the file, try using the Image Processing API.
To process files from any URL at runtime:
Create a folder in the Bytescale Dashboard.
Edit the folder's settings.
Click on "Storage Settings".
Change "Storage Type" to "External HTTP URL".
For "Use a Base URL" select "No"
Click on "Save Changes". (Don't forget this step before continuing!)
Try it out:
Copy the "Example URL" from the UI.
Replace "https://assets.bytescale.com/example.jpg" with a URL you want to fetch.
To process the file, try using the Image Processing API.
