Generally, you should have a working Ignite cluster somewhere that will
store and process your requests.
I am not sure that you really require the client node in your case. It will
use additional memory and CPU.
You can use several ways to work with Ignite cluster without fat client
1)Thin clients (ODBC/JDBC) - you may store the connection open but it could
be closed. So you can try to use some connection pull.
2)REST - just open the connection and do some operations. Also could be
timed out. So you could open a new connection for every update.
