@diegovsky @pid_eins Varlink streaming is supported when using the websocket, its pretty nice with the new varlink-protocol feature of systemd v260+: `varlinkctl call --more http://localhost:1031/ws/sockets/io.systemd.JournalAccess io.systemd.JournalAccess.GetEntries {}`. The regular API does not currently support streaming, I was thinking we could add it via SSE but not fully sure yet
