I've been reading Ignite official document and going through Ignite source code for a few while now.
>From the source code I see that Ignite can be a key/value store and the data is stored in a ConcurrentHashMap for every partition. So this is one copy of data in memory. For Ignite SQL function, it seems like Ignite creates a H2 table in memory based on the fields user want to be query with SQL. So does it mean for every key with @QuerySqlField annotation, there will be two copies of data in memory(one in ConcurrentHashMap and one in in-memory H2 table)? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
