Alfonso Nishikawa commented on GORA-207:
----------------------------------------
Commited GORA-207_over_r1465660.patch to /branches/GORA_174 as #1480130 (over
#1477735) fixing some bugs.
Full support of unions (2 types unions, 3 types unions,...) :
- Support of ["null",type] (a.k.a. optional field).
- Support for mutitypes(3+) unions.
- Support of nested unions.
- Support of recursive optional records.
- Support of unions as value in maps and arrays.
- Serialization of topmost optional fields of the main record in "raw": topmost
["null","type"] (optional field) will be persisted like if it was ["type"] (and
non-existant column === null). This ensures data form 0.2.1 can be read.
> Verify storage and retrieval of Avro Union data type within Gora-HBase
