Stefan Miklosovic commented on CASSANDRA-13855:
-----------------------------------------------
The problem I see is that if we e.g. talk about that EC2SeedProvider as in that
link above, it uses some AWS libraries. If we wanted to ship it with Cassandra,
we would have to depend on this library and this would be done for each such
cloud. That opens a can of worms ... Are licences compatible? What version of
that library are we going to use? Who is going to update it and when? Are these
libraries even compatible between themselves when we put the on the class path?
They might depend on various libraries themselves, are we going to ship all of
that with the project too?
The task here is to code up a "HTTP seed provider" -> HTTP meaning it would
read some external data in a predefined format which would be parsed and it is
responsibility of a user to provide such HTTP endpoint to read the metadata
from. Cloud snitches are modelled like that too - they are just using HTTP to
call cloud metadata services just in different ways. It would be possible to
not depend on cloud libraries but to code cloud snitches in such a way that
they would be still using HTTP under the hood?
Secondly, the point is to return, from a seed provider, list of addresses which
are supposed to be seeds. I just do not see how putting a snitch into a seed
provider achieves this.
