URL: https://github.com/apache/incubator-paimon/issues/735#issuecomment-1492181024

   clickhouse support  the feature by `ALTER TABLE`, like `ALTER TABLE events
   ADD COLUMN mat_$current_url
   VARCHAR MATERIALIZED JSONExtractString(properties_json, '$current_url')` ,but  flink and spark  do not support the statement, do we implement it by add some properties?
