[GitHub] [druid] josephglanville opened a new issue #10493: Avro Union type support
josephglanville opened a new issue #10493:
URL: https://github.com/apache/druid/issues/10493
### Description
Avro unions should be supported for ingestion into Druid, currently only the specific form `[null, someOtherType]` is supported and is treated as a form of nullable.
I propose having Druid explode unions at ingestion time via the flattener interface into nested paths accessible by the union member type name. i.e If I have the following Avro schema:
```
{
"name" : "union",
"type" : [ "null", "string", "boolean", "float", "int" ]
}
```
Then I should be able to access each of the member types as `union.typeName`, i.e: `union.string`, `union.boolean`, `union.float` and `union.int` in this case.
### Motivation
This will expand Druid's Avro support to cover the full spec as of right now there is valid Avro that can't be meaningfully ingested into Druid without pre-processing to remove unions.
