[jira] [Created] (IMPALA-11876) Support fixed type in AVRO

Noemi Pap-Takacs created IMPALA-11876:
-----------------------------------------

             Summary: Support fixed type in AVRO
                 Key: IMPALA-11876
                 URL: https://issues.apache.org/jira/browse/IMPALA-11876
             Project: IMPALA
          Issue Type: New Feature
          Components: Backend
            Reporter: Noemi Pap-Takacs
            Assignee: Noemi Pap-Takacs


Impala supports 'decimal' type in AVRO. 'Decimal' is a logical type, that can annotate either 'bytes' or 'fixed' type underneath. Impala can read 'bytes' but not 'fixed'.
Iceberg writes 'decimal' type with underlying 'fixed' type. This means that Impala is currently unable to support 'decimal' in AVRO tables written by Iceberg. In order to fully support all implementations of 'decimal', 'fixed' type must be supported.
