This page <https://calcite.apache.org/avatica/docs/roadmap.html> says that DML statements aren't supported. While this page <https://calcite.apache.org/news/2017/01/09/release-1.11.0/> says it can push down DML actions.
What exactly does the first page mean by that DMLs aren't supported ? Is it referring to parsing or pushing-down DML statements ? Thanks, Gelbana
