Hi, Dev

I would like to start a discussion about FLIP-448: Introduce Pluggable
Workflow Scheduler Interface for Materialized Table.

In FLIP-435[1], we proposed Materialized Table, which has two types of data
refresh modes: Full Refresh & Continuous Refresh Mode. In Full Refresh
mode, the Materialized Table relies on a workflow scheduler to perform
periodic refresh operation to achieve the desired data freshness.

There are numerous open-source workflow schedulers available, with popular
ones including Airflow and DolphinScheduler. To enable Materialized Table
to work with different workflow schedulers, we propose a pluggable workflow
scheduler interface for Materialized Table in this FLIP.

For more details, see FLIP-448 [2]. Looking forward to your feedback.
