I'm a little confused about the support of cloud endpoints for cloud functions in GCP.
In the documentation page for endpoints for cloud functions it states that right now there's a beta phase for ESP v2 and clearly explains how to configure them. From this sentence it seems to me that there's some sort of GA version of ESP for functions:
Previous releases of Cloud Endpoints supported the use of the Extensible Service Proxy (ESP) with Cloud Functions
But I can't find any documentation about ESP in specific.
I would like to understand two things:
1) when did ESP v2 enter the beta phase ? Is there an estimate time for the GA launch ?
2) Is there a GA version of cloud endpoints for cloud functions ?
Maybe someone already tried to implement this in the past and can tell me a little bit of history about ESP and ESP v2 migration, to understand if choosing this over cloud endpoints framework is worth the shoot.
