Stabilize Array DataType Support. This is umbrella jira to track all related

||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 Array data needs to
convert from spark datatype to string , as carbon takes string as input row |
|Support DDL for Array fields Dictionary include and Dictionary Exclude |
Develop | Also needs to handle CarbonDictionaryDecoder to handle the same. |
|Support multilevel Array | Develop | currently DDL is validated to allow only
2 levels, remove this restriction|
|Support Array value to be a measure | Develop | Currently supports only
dimensions |
|Support Alter table to add and remove Array column | Develop | implement DDL
and requires default value handling |
|Projections of Array values push down to carbon | Develop | this is an
optimization, when more number of values are present in Array |
|Filter Array values push down to carbon | Develop | this is an optimization,
when more number of values are present in Array |
