> Stabilize Array 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 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 |
> |Update Array values | Develop | update array value|
