Hi Alexandr, Ignite is a good fit for your use case. (4) and (5) can be achieved via Continuous Query [1] with a remote filter and local listener:
- create an Ignite cache to store messages (use expiration to store temporarily) - start a continuous query on all servers with a remote filter and local listener - add messages to cache, include receiver user name - remote filter analyses the message and accepts only messages which are for the users on the current server - local listener delivers the message through WebSocket Let me know if this helps.
