> Support automatic recursion removal from schemas
> ------------------------------------------------
>
> Key: GOBBLIN-957
> URL: https://issues.apache.org/jira/browse/GOBBLIN-957
> Project: Apache Gobblin
> Issue Type: Improvement
> Reporter: Shirshanka Das
> Assignee: Shirshanka Das
> Priority: Major
> Labels: avro
> Time Spent: 1h
> Remaining Estimate: 0h
>
> Analytics engines like Hive etc cannot handle recursive schemas: schemas
> where inner fields can refer to the wrapping type.
> This Jira proposes that we provide support for automatic recursion removal in
> data during data ingestion.
> The simple proposal is to just drop the fields in the schema that introduce
> the recursion.
> e.g. (pseudo-schema)
> User {
> string name;
> User friend;
> }
> gets converted to :
> User {
> string name;
> }
>
> A more sophisticated solution would be to do one or two levels of
> "schema-unrolling" before dropping data.
> e.g.
> output schema with one-level unrolling would look like:
> User {
> string name;
> User1 friend;
> }
> User 1 {
> string name;
> }
>
>
