Konstantin Orlov updated IGNITE-17704:
--------------------------------------
Description:
Execution-related classes have no third-party dependencies except for apache
calcite. The only thing connecting them is the RelDataType class, describing a
type of the row.
Seems the only actual usage of row type is inside
{{CorrelatedNestedLoopJoinNode}}.
So let's get rid of unnecessary coupling by reworking
{{CorrelatedNestedLoopJoinNode}} class.
was:
We use calcite class org.apache.calcite.rel.type.RelDataType in our execution
node representation
org.apache.ignite.internal.sql.engine.exec.rel.AbstractNode.
Let's get rid of such dependency
