when persistence enabled, when call IgniteCache.put(k,v) with a `NEW` key-value pair, it's obviously that there is a new `INSERT` sql generated and the values will be inserted into the backend table.
but for the case when I want to update the properties of the value entity (eg, the weight property of Dog entity) if call via IgniteCache.put(k,v), how the backend Sqls issued ? 1 : use two sqls: first issue a `DELETE` and then issue a `INSERT`? 2: use single sql: `UPDATE` including`ALL` properties(columns) 3: or ignite is smart enough just to update the `CHANGED` properties(columns) with a single update? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
