xKey Maintenance Mode: what does this mean long-term?

[Peter Bowyer]

Hi,

I'm one of the small-time Varnish users. Nothing I do is high traffic, but
I use Varnish because it gives users a faster experience, lets me use cheap
servers, and because it's a pleasure to use.

xKey is a feature I use because it lets me easily flush dynamic HTML pages
from the cache, for the whole site or for sections of it.

xKey is now in maintenance mode [1]. It's great that it is still
maintained. But it does give me concern about the future. Will Varnish (the
corporation) open-source yKey? Is there an alternative planned in Varnish
(the open source project)?


Two tangents.
1. Drupal went their own way instead of using xKey and use a BAN with a
regex (a regex which has been wrong until recently [2]). Can anyone
estimate how much less performant this is than xKey?

2. The maintenance mode notice points us at yKey. I'd like to use the VMODs
from Varnish (the corporation) for their DX and have offered them money
multiple times, but their starting price for a license is usually more than
the entire annual cost for the digital infrastructure of projects I work
on. If anyone from the corporation is reading, t's a shame there's no SME
licensing.
