Venkata Ramana G updated CARBONDATA-1457:
-----------------------------------------
Description:
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 |
