Key: CALCITE-4770
URL: https://issues.apache.org/jira/browse/CALCITE-4770
Project: Calcite
Issue Type: New Feature
Reporter: xzh_dz
In the data system, materialized view can speed up SQL query. Materialized view
represents the pre-calculated SQL logic of the target table and contains real
data. In the project, we use materialized views to speed up SQL queries, use
the materialized view recognition technology to identify materialized views,
and enhance the ability of materialized recognition. However, with more and
more materialized views , materialized view recognition takes a lot of time,
which seriously affects the performance of SQL queries. With this problem, we
propose a design of accurate search materialized view based on operator
features.
