[Discussion]Float and Double compatibility issue with external segments to Carbon
Need a help!!
Was trying to create a carbon table with float field. I understand that
internally it stores float as double in its schema.
When we try to add an externa segment with float field, add segment/queries
on ext segment would not be successful due to datatype mismatch.
create table carbon_float(c1 float) stored as carbondata
desc formatted carbon_float
// hive table shows datatype as double.
// create another table with same schema
create table orc_float4(c1 float) using orc
insert into orc_float4 select 1
