Firebase function v2 is here. Now as per the docs:

Function instances can now execute more than one request at a time. This feature is available for functions with one dedicated CPU or higher. Concurrency levels can be set on a per-function basis or across all functions with the setGlobalOptions method. If unspecified, new functions with 1 dedicated CPU or higher will default to 80 concurrent requests. See Allow concurrent requests.

Now my doubt is if a Function instance spun up for handling functionX will also receive traffic for functionY? OR, this means functionX instance will receive concurrent traffic only for just functionX?

CodePudding user response：

Firebaser here. An instance of functionX will only receive concurrent traffic for functionX. In Cloud Functions for Firebase, an instance always only consists of a single function (functionX or functionY, never both).
