If you don’t use SQL, Ignite is basically a key-value store. That is, if you
don’t know the key you have to look at every record to see if it matches.
You can specify a filter on the ScanQuery:
ScanQuery<String,Integer> q = new ScanQuery<>((k,v) -> k.equals("Stephen"));
That wouldn’t be indexed, though. If you have a lot of records this isn’t going
to be very efficient.
