------------------------------------
Summary: Print the retainMissing flag for SelectOperator if the
flag is true
Key: ASTERIXDB-1638
URL: https://issues.apache.org/jira/browse/ASTERIXDB-1638
Project: Apache AsterixDB
Issue Type: Bug
Reporter: Yingyi Bu
Assignee: Yingyi Bu
Priority: Minor
There is a retainMissing flag in the select operator. That's set to be true for
the select operator that results from an index left outer join rewriting, e.g.:
select (function-call: algebricks:and, Args:[function-call: algebricks:neq,
Args:[%0->$$26, %0->$$25], function-call: asterix:get-item,
Args:[function-call: asterix:similarity-jaccard-check, Args:[%0->$$29,
%0->$$30, AFloat:
{0.6}], AInt64: {0}]]) – |LOCAL|
It would be helpful to print that flag in the plan, e.g.:
select *[retainMissing=true]* (function-call: algebricks:and,
Args:[function-call: algebricks:neq, Args:[%0->$$26, %0->$$25], function-call:
asterix:get-item, Args:[function-call: asterix:similarity-jaccard-check,
Args:[%0->$$29, %0->$$30, AFloat: {0.6}
], AInt64:
{0}
]]) – |LOCAL|
