Support Array and ExprValue Parsing With Inner Hits #1737

forestmvey · 2023-06-14T16:39:43Z

Description

With the addition of the nested function support in the V2 engine the inner_hits portion of the OS response needs to be parsed for OS types. Previously arrays were not entirely parsed due to lack of support.

Parsing Functionality

Parsing of each value in arrays needs to be supported for proper nested functionality. The following gives examples of the current response formats when parsing arrays.

Object Type - Array Of Objects

Dataset:
"obj": [{"key": "val1"}, {"key": "val2"}]

SQL Query:

SELECT obj FROM objects;

V1 Engine Response:
[{'key': 'val1'},{'key': 'val2'}]

V2 Engine Response:
{'key': 'val1'}

Nested Type - Array Of Objects

Dataset:
"obj": [{"key": "val1"}, {"key": "val2"}]

SQL Query:

SELECT obj FROM nested_objects;

V1 and V2 Engine Response:
[{'key': 'val1'},{'key': 'val2'}]

Array Of Values (Nested only supports objects and not arrays of values):

Dataset:
"obj": ["val1", "val2"]

SQL Query:

SELECT obj FROM objects;

V1 Engine Response:
['val1','val2']

V2 Engine Response:
{'val1'}

did we want to test this with a nested type too?

This is a inner object to the nested object address. We have IT tests to test with the nested function in NestedIT.java#L373-L400. Is this what you were thinking of testing?

Yes. I think I was wondering if we had nested within nested.

Yes we already have tests for nested in nested too.

what would be the data type of nested(address.moveInDate), object or array?

It would be of type object. address would be of type nested, I'll add the schema verification.

i see. one more question.
some rows is JSONObject, some rows are JSONArray, how does JDBC handle it?

In some cases this breaks JDBC, but there is no change in the expected output with this PR. An example of this would be in ObjectFieldSelectIT where we do a select on an OBJECT type array, and a NESTED type array.

ObjectFieldSelectIT.java#L69-L93
people.json
people-mapping

When selecting on an array that is not of type NESTED, the first value in the array is returned and is functional with JDBC. As shown by the query:

SELECT accounts FROM people;

While on the other hand the query that does a basic SELECT on an NESTED type array returns the whole array which breaks JDBC.

Query:

SELECT projects FROM people;

A user can get around this by using the nested function to flatten the response for a correct JDBC output.

ignore my comments below.
what if the data is? the expected stringV is [["zz", "au"], ["ss"], ["z"]], right?

{ "stringV": ["z", ["s"], ["zz", "au"]] }

If we execute on this:

tupleValueWithArraySupport("{"stringV": ["z", ["s"], ["zz", "au"]]}").get("stringV");

The resulting value is:

["z", ["s"], ["zz", "au"]]

In your example the order is reversed which is not the case. Does this answer your question?

If you are using something with type of SHORT or BYTE does it get cast/treated as an INTEGER before this point or does it need to be supported?

Treated as an integer. No need to cast or treat differently.
