C* supports "optional" encryption, that is, it supports clients that can connect both via TCP as well as TLS (on the same port). If we enable this in C*'s config,...

Right now if a control connection to a node goes down, we try to reconnect forever. This is an issue because C* cluster topologies evolve in time. For example, we...

autodiscovery: true opens connections to new nodes in other data centers

4

The [documentation](https://hexdocs.pm/xandra/Xandra.Cluster.html#module-autodiscovery) states that: >When nodes in the cluster are discovered, a Xandra pool of connections is started for each node that is in the same datacenter as one of...

All other C* drivers built by Datastax (for Python, PHP, Java, Ruby, Node) to this and are successful 😄 I [asked about this](https://community.datastax.com/questions/13895/how-many-control-connection-to-start.html) in Datastax's forums and they confirmed that...

Work in progress. Addresses https://github.com/lexhide/xandra/issues/199. #### Introduces `:autodiscover_other_datacenters` option When `false`, Xandra will ignore topology change events describing new nodes in datacenters it never opened control connections to. When `true`,...
