daemon nodes

[Dmitriy Govorukhin]

Hi Igniters,

Can somebody explain what does mean  daemon node? I thought that exist
only client and server node, but node may can be daemon (server daemon
or client daemon).  As is can see, command line visor join in topology
as server daemon. Can this be an outdated functionality?

Daemon nodes are nodes that join the cluster, but do not store data or
execute computations or perform any other of the Ignite API-based
functionality. Visor node is a good example of a daemon node, because it
wants to join the cluster and receive metrics from other nodes, but does
not need to participate in computation or data related functionality.

Dmitriy,

Why daemon node may be server or client? Why it is not just daemon? I
guess if daemon " do not store data or
execute computations " it must be always client daemon. For me, daemon
server, very strange.

Some messages don't go through clients. May be some daemon realization will
need them?

What kind of messages are you talking about? Please, provide example.

Hi,
ok, if we have 3 type of nodes: - clients - servers - daemons. Let us merge
all types of daemons in one daemon type and remove unused code for server
daemon. Are there any concerns about this idea?

Best Regards,
Dmitry Pavlov

Dmitriy Govorukhin, ServerImpl
process TcpDiscoveryJoinRequestMessage,
TcpDiscoveryStatusCheckMessage, TcpDiscoveryDiscardMessage
and TcpDiscoveryRingLatencyCheckMessage while ClientImpl
process TcpDiscoveryPingRequest. Thats the difference I see between server
and client node message workers.

Agree, daemons can always be a client. Dmitry G, I doubt if we should
bother with this right now, but can you please create a ticket that will
imply client mode for daemons. Probably, community can pick it up.

Yakov,

I created jira issue IGNITE-5603
<https://issues.apache.org/jira/browse/IGNITE-5603>.

Whoever has an objection related this task?
