Convert struct to map in Spark SQL

Asked 2021-Dec-20 at 12:40

I am trying to convert one dataset which declares a column to have a certain struct type (eg. struct) to a map type. And I would like to do it in SQL, possibly without using UDFs.

UPDATE:

My requirement is also that the transformation is done generically without any prior knowledge of the struct keys (in my problem I am getting data in a complex JSON, and I don't want to keep that complexity in the schema).

Example input data:

ANSWER

Answered 2021-Dec-17 at 13:00

I have found a way to do it which requires one roundtrip of serializing and parsing a json using the to_json and from_json functions. The trick is that the from_json also takes a schema argument where I use the map type.

Also, this solution should work with spark < 3.x

ANSWER

Answered 2021-Sep-12 at 00:27

The error is being caused because the reference returned by left("office_id") no longer exists in the new projected dataset(i.e. the dataset resulting from the first join and map operation).

If you look closer at the execution plan in the nested relation

: +- LocalRelation , [id#40L, proj_id#41L, office_id#42L, salary#43L]

you can observe that the reference to office_id in the left dataset is office_id#42L. However, if you look at the later execution, you will notice that this reference no longer exists in the projection

SerializeFromObject [assertnotnull(assertnotnull(input[0, Employee, true])).id AS id#114L, assertnotnull(assertnotnull(input[0, Employee, true])).proj_id AS proj_id#115L, assertnotnull(assertnotnull(input[0, Employee, true])).office_id AS office_id#116L, assertnotnull(assertnotnull(input[0, Employee, true])).salary AS salary#117L]

as the office_id reference available is office_id#116L.

In order to resolve this, you could use intermediary/temporary variables eg:

First off, make sure you are using Delta Lake as the table format. Second, I think you are looking for Upserts, which are defined as

An operation that inserts rows into a database table if they do not already exist, or updates them if they do.

To do so you'll need to use MERGE combined with UPDATE. Here's an example with the matching expression:

How to convert a DataFrame map column to a struct column?

Asked 2020-Jun-05 at 16:03

Suppose we have a DataFrame with a column of map type. What is the most straightforward way to convert it to a struct (or, equivalently, define a new column with the same keys and values but as a struct type)? See the following spark-shell (2.4.5) session, for an insanely inefficient way of going about it:

Spark INLINE Vs. LATERAL VIEW EXPLODE differences?

Asked 2020-May-30 at 08:14

In Spark, for the following use case, I'd like to understand what are the main differences between using the INLINE and EXPLODE ... I'm not sure if there are any performance implications or if one method is preferred over the other one or if there are any other uses cases where one is appropriate and the other is not...

The use case is to select 2 fields from a complex data type (array of structs), my instinct was to use INLINE since it explodes an array of structs

For example:
