## Proposed changes
Support to use current_date() when create async materialized view by adding
`'enable_date_nondeterministic_function' = 'true'` in properties when create
materialized view. `enable_date_nondeterministic_function` is default false.
Here is a example, it will success
`
CREATE MATERIALIZED VIEW mv_name
BUILD DEFERRED REFRESH AUTO ON MANUAL
DISTRIBUTED BY RANDOM BUCKETS 2
PROPERTIES (
'replication_num' = '1',
'enable_date_nondeterministic_function' = 'true'
)
AS
SELECT *, unix_timestamp(k3, '%Y-%m-%d %H:%i-%s') from ${tableName}
where current_date() > k3;
`
Note:
`unix_timestamp` is nondeterministic when has no params. it is deterministic
when has params which means format column k3 date
another example, it will fail
`
CREATE MATERIALIZED VIEW mv_name
BUILD DEFERRED REFRESH AUTO ON MANUAL
DISTRIBUTED BY RANDOM BUCKETS 2
PROPERTIES (
'replication_num' = '1',
'enable_date_nondeterministic_function' = 'true'
)
AS
SELECT *, unix_timestamp() from ${tableName} where current_date() >
k3;
`
because `unix_timestamp()` is nondeterministic
