Hi,

Yes, you need to use ScanQuery[1] over partition (look at the
setPartition(int)[1] method). The query will be iterate over entry in a
particular partition.

To aware which partitions are storing in local node, use the code snippet:

Affinity aff = ignite.affinity(cacheName);
ClusterNode locNode = ignite.cluster().localNode();
int[] parts = aff.primaryPartitions(locNode);

Is it possible to iterate through all key values on primary partition of
the node on this node?

Thanks,
Yitzhak

IgniteCache is Iterable, so you can just iterate through its contents.

-Val
