> Stabilize Struct DataType Support. This is umbrella jira to track all related tasks.
> Following cases needs to be handled:
> ||Sub feature||Pending activity||Remarks||
> |query, filter, NULL values, UDFs, Describe support|Test + Fix|Implementation in place needs to add test-cases and bug fix|
> |Compaction support | Test + fix | As compaction works at byte level, no changes required. Needs to add test-cases|
> |Insert into table| Develop | Source table data containing struct data needs to convert from spark datatype to string , as carbon takes string as input row |
> |Support DDL for Struct fields Dictionary include and Dictionary Exclude | Develop | Also needs to handle CarbonDictionaryDecoder to handle the same. |
> |Support multilevel struct | Develop | currently DDL is validated to allow only 2 levels, remove this restriction|
> |Support struct field to be a measure | Develop | Currently supports only dimensions |
> |Support Alter table to add and remove struct column | Develop | implement DDL and requires default value handling |
> |Projections of struct fields push down to carbon | Develop | this is an optimization, when more number of fields are present in struct |
> |Filter struct fields push down to carbon | Develop | this is an optimization, when more number of fields are present in struct |
> |Struct fields participate in sort column | Develop | This is can be low priority |
