https://issues.apache.org/jira/browse/CARBONDATA-4178> Project: CarbonData
> Issue Type: Bug
> Components: presto-integration
> Affects Versions: 2.1.1
> Environment: Spark 2.4.5. Presto 316
> Reporter: Chetan Bhat
> Priority: Minor

> Steps -
> From Spark session the table creation and insert operations are executed as shown below
>
> drop table if exists complextable;
> create table complextable (id string, country array<string>, name string) stored as carbondata;
> insert into complextable select 1, array('china', 'us'), 'b' union all select 2, array ('pak', 'india', 'china'), 'v';
> From presto cli the below queries are executed.
> select * from complextable ;
> select * from complextable where country[3]='china';
>
> Issue - if we insert different no of data in array complex datatype. then query filter on increment or last index gives error from presto
