Description

In case of tables with deeply nested structures this issue with unnecessary String concatenations in the RexFieldAccess constructor started to play significant role

and we faced it already.

Since the fix (CALCITE-5965) is only in Calcite 1.36.0 it can take a long time before it comes with Calcite upgrade (currently there are 1.33 and 1.34 in ready for review only)
