These limitations are unique for each resource tier. There are currently three resource tiers available, Dynamic Compute, Basic Compute and Enterprise Compute.
👍 The limits for the EdgeWorker IDs created without a resource tier will not change. By default, these EdgeWorkers functions will execute using Dynamic Compute. The Dynamic Compute limits are the same as the limits applied prior to the introduction of resource tiers.

Note: You can use content fetched using the onClientRequest event handler to modify the original end-user request’s cache key. For cache keys modified in this way, you need to use purge by CP Code and not by URL. For instructions on how to purge a CP code see Purge Content by CP code. For instructions on how to create a CP code see Create a CP code.
