Limitations
Keep these limitations in mind when designing functions to execute on the edge.
| Description | Limit |
|---|---|
| Number of activated EdgeWorker scripts per account | 5000 per network |
| Number of EdgeWorker scripts executed per request | 1 |
| Compressed size for a code bundle | 512 KB |
| Uncompressed size for a code bundle | 1 MB |
| Edge constructed HTTP response body size | 2048 characters Note: This limitation only applies to the
respondWith() method. |
| Maximum size of a response body when using the json() and text() methods from the HttpResponse Object | 128 KB |
| JavaScript initialization timeout Note: The JavaScript initialization time
includes the Akamai setup and customer code compile. |
100 milliseconds |
| JavaScript CPU initialization timeout | 30 milliseconds |
| CPU timeout for the onClientRequest, onOriginRequest, onOriginResponse, and onClientResponse event handlers | 10 milliseconds |
| CPU timeout for the responseProvider event handler | 100 milliseconds |
| Memory limit per onClientRequest, onOriginRequest, onOriginResponse, and onClientResponse event handler | 1 MB |
| Memory limit per responseProvider event handler | 2 MB |
| Wall time limit for the onClientRequest, onOriginRequest, On OriginResponse, and onClientResponse event handlers | 100 milliseconds |
| Wall time limit for the responseProvider event handler | 4 seconds |
| Supported delivery products | Ion Dynamic Site Accelerator (DSA)Adaptive Media DeliveryDownload DeliveryObject DeliveryAPI Acceleration |
| Supported delivery network | Enhanced TLS Note: When you've applied a custom certificate to a property configuration, the
associated Edge hostname uses the .edgekey.net
domain.Note: Standard TLS,
used to serve non PCI compliant traffic over HTTP or HTTPS via an edgesuite.net
edge hostname, is not supported. |
| HTTP sub-requests | Limit |
|---|---|
| Number of HTTP sub-requests per request | 50 |
| Number of concurrent HTTP sub-requests per event handler | 5 |
| Maximum buffered response size for HTTP sub-requests from the responseProvider handler | 1 MB Note: This limit does not apply to streamed
responses. |
| HTTP sub-request timeout for the responseProvider event handler | 1 second |
