Thanks Vladmir. Unfortunately we need write-through to guarantee persistence. Which means we'll need to modify approach so that client nodes are allowed to write to the store. You also wrote that ATOMIC cache doesn't give any transactional guarantees. Does it mean that if we have write-through cac

Re: Server node info when client disconnects

Hi Alper, I'm not sure I understand the issue and the fix. EVT_NODE_LEFT/FAILED and EVT_CLIENT_NODE_DISCONNECTED are different events that are fired in different situations. For example, EVT_CLIENT_NODE_DISCONNECTED can happen due to network outage, even without any server failures. And on the ot

Alexander, from my point of view you should use only server nodes because Vert.x use cluster manager distributed datastructures (caches in case of Ignite) for storing information about event bus subscribers and deployed verticles. In order to reduce memory footprint you can also reduce the follow

Re: Reducing memory footprint

Alexander, No, there is no way to change cache topology in runtime. Client node doesn't store any data and by default never executes jobs or runs services. It also uses more lightweight discovery protocol, which allows to have a lot of clients to be connected to a single cluster. But I'm still a
