> {code}
> create table t1(a int, b int, c int) stored as parquet TBLPROPERTIES ('transactional'='true', 'transactional_properties'='insert_only');
> create materialized view mat1 stored as orc TBLPROPERTIES ('transactional'='true') as
> select a, b, c from t1 where a > 10;
> {code}
> Currently materialized view *mat1* can not be rebuilt incrementally because it has an insert only source table (t1). Such tables does not have ROW_ID.write_id which is required to identify newly inserted records since the last rebuild.
> HIVE-25406 adds the ability to query write_id.
