---------------------------------
Labels: triaged (was: )
> Adding support for heterogeneous index
> --------------------------------------
>
> Key: ASTERIXDB-3536
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-3536
> Project: Apache AsterixDB
> Issue Type: Improvement
> Components: COMP - Compiler
> Reporter: shahrzad shirazi
> Priority: Minor
> Labels: triaged
>
> A Heterogeneous Index allows creating an index on a field without specifying
> its type. This means the field’s type no longer needs to be defined in the
> data type or the index creation DDL.
> Previously, creating a secondary index required the field's type to be
> defined either in the data type or explicitly in the index DDL, making it
> impossible to index heterogeneous fields.
>
> example:
> {code:java}
> CREATE TYPE UserType AS { userId : int};
> CREATE DATASET UserTypes(UserType) primary key userId;
> // Creating a heterogeneous index on the field age
> CREATE Index idx_user_age on UserTypes(age);{code}
>
