Hi Jeff
Today, we use proxy nodes with php, and we are migrating from php to java.
Our farm of php servers is made of 80 physical servers, all of them having
a local proxy node.
So our cassandra cluster is made of :
- DC1 : 6 data nodes + 40 proxies
- DC2 : 6 data nodes + 40 proxies
During our t
Hi Stefan,
Your analysis is exactly what happen !
What I can say is that we are migrating from php to java and the behaviour
of the php (or cpp) driver is completely different.
* The topology of the cassandra cluster returned by the contact point with
the php driver includes data nodes + proxy no
proxy went down?

Just to be clear:
- How many of the proxy nodes are you providing as contact points? One of
them or all of them?
It sounds like you're saying you're passing all of them, and only one is
connecting, and the driver is declining to connect to the rest because
they're not in system.peers. I'm not sur
We have tested Stargate and were very disappointed...
Originally our architecture was PHP microservices (with FPM) + cassandra
proxies.
But we were blocked because PHP driver is no more supported.
We made tests to keep PHP + stargate but there were many issues, the main
one (but not the only one)
Those nodes are not in the peers table(s) because you told them NOT to join
the ring with `join_ring=false` so it is working by design.
I'm not really sure what you're trying to achieve but if you want to
separate the coordinator functions from the storage then what you probably
want is to deploy
ata.

CASSANDRA-526 provides this ability, I just want to make sure,
let's say I have one node, with token 0, and now I want to add 2 new
ones, with initial_token set at 1/3 and 2/3 of the full range.
now I start nodes 2 and 3 with the -DCassandra.join_ring=false option,
and later use JMX joi
