Hi Evgenii,
Are you saying that if the affinityKey column is present in WHERE clause of
SQL statement, the SQL engine will detect a node where this key is placed
and execute this query only on one node.
I just want to make sure that SQL gets executed only on node where the
affinity key is placed.
Yes, that’s exactly how Ignite SQL works by default.

secondary for that data)

Hello!
I hope that Ignite statement planner will make use of affinity key if you
provide it in the request. I.e. it will not be broadcast if you provide
affinity key.

When you run SQL query with filtering on Affinity key field, the SQL engine
will detect a node where this key is placed and execute this query only on
one node.
What are you trying to achieve?

What do you mean by “execute select query on cache using affinity key”
and what is the problem you’re trying to solve?
