Summary: Support masking queries containing correlated collection
references
Key: IMPALA-9330
URL: https://issues.apache.org/jira/browse/IMPALA-9330
Project: IMPALA
Issue Type: Improvement
Reporter: Quanlong Huang
Assignee: Quanlong Huang
Let's say table complextypestbl (id bigint, int_arr array<int>) has column
masking policy on id: "id => id * 100". The following query is not rewritten
correctly:
{code:sql}
select t.id, a.pos, a.item from complextypestbl t, t.int_arr a;
{code}
Because its AST will be rewritten to the AST of
{code:sql}
select t.id, a.pos, a.item from (
select cast(id * 100 as BIGINT) id
from complextypestbl
) t, t.int_arr a;
{code}
Currently, the analyzer can't resolve "t.int_arr" correctly.
