-------------------------------------------
Summary: Sql. Align RexImpTable implementation according to
calcite current version.
Key: IGNITE-19130
URL: https://issues.apache.org/jira/browse/IGNITE-19130
Project: Ignite
Issue Type: Improvement
Components: sql
Affects Versions: 3.0.0-beta1
Reporter: Evgeny Stanilovsky
RexImpTable in apache ignite for now is a copy from old apache calcite, some
functions already changed implementation and some additionally introduced (fow
example ARG_MIN, ARG_MAX [1]) but apache ignite is not supported them due to
outdated RexImpTable implementation. Propose:
1. Somehow documented why we need such approach.
2. If only this way is convenient for now - copy actual implementation, change
involved functions\fields access i.e. from private to protected and
use\override appropriate methods in descendant implementation.
