How to do cache.get() on SQL table by primary key with multiple columns?

[John Smith]

Hi, I have an SQL table

create table if not exists my_table (
column1 int,
column2 int,
column3 varchar(16),
PRIMARY KEY (column1, column2)
) with "template=replicatedTpl";

and I'm creating my near cache as follows...

IgniteCache<Integer, String> myCache;

NearCacheConfiguration<Integer, String> nearConfig = new
NearCacheConfiguration<>();
nearConfig.setNearEvictionPolicyFactory(new
LruEvictionPolicyFactory<>(1024));

myCache =
this.ignite.getOrCreateNearCache(SQL_PUBLIC_MY_TABLE, nearConfig)
.withExpiryPolicy(new AccessedExpiryPolicy(new Duration(TimeUnit.HOURS,
1)));

So if I use myCache.get()...

1- How do I specify the primary key if it's 2 columns?
2- I assume the data will be put in near cache?
