[jira] [Updated] (GORA-223) Verify storage and retrieval of Avro
Union data type in nested structures within Gora-Cassandra
[ https://issues.apache.org/jira/browse/GORA-223?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lewis John McGibbney updated GORA-223:
--------------------------------------
Description:
Post GORA-174 and GORA-206 gora-cassandra does not support the following data models
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.
This issue should address all of the above which will bring gora-cassandra up to speed with other module's post- GORA-174
