Thanks Evgenii. I am still a little bit confused.
So if my CustomKey is composed of Client_ID, Customer_ID, and other fields
are Customer_name, Client_name, then I populate the cache this way? Do I
need to build two binary objects, one for the custom key and another for
the rest of the fields?
IgniteDataStreamer<CustomKey, BinaryObject> streamer =
grid.dataStreamer("Customer");
streamer.keepBinary(true);
BinaryObjectBuilder builder1 = ignite.binary().builder("keys");
BinaryObjectBuilder builder2 = ignite.binary().builder("fields");
BinaryObject b1 = null;
BinaryObject b2 = null;
builder1.setField("Client_ID", 1);
builder1.setField("Customer_ID", 1);
builder2.setField("customer_name", "jim");
builder2.setField("client_name", "joe");
b1 = builder1.build();
b2 = builder2.build;
streamer.adddata(b1, b2);
