To be simple where the records for "Person" & > "Department" would be stored and how that can be configured Think of a cache as of a table in an RBMS. So “Person” and “Department” will be stored in separate caches. Data grid (key-value) examples should boost your plunging into Ignite concepts: https://github.com/apache/ignite/tree/master/examples/src/main/java/org/apache/ignite/examples/datagrid <https://github.com/apache/ignite/tree/master/examples/src/main/java/org/apache/ignite/examples/datagrid> — Denis > > Thanks, > Rajesh > > On Wed, Jan 17, 2018 at 5:37 PM, Mikael <mikael-arons...@telia.com > <mailto:mikael-arons...@telia.com>> wrote: > There are lots of examples not using SQL, have a look at: > > https://apacheignite.readme.io/docs/jcache > <https://apacheignite.readme.io/docs/jcache> > Ignite implements the JCache API, just use get/put and so on. > > > Den 2018-01-17 kl. 12:44, skrev Rajesh Kishore: >> This is much informative.
