Hi all:
Hope the statement not seems too dash to you.
Drill claims be a schema-free distributed SQL engine. It pays lots of
work to make the execution engine to support it to support JSON file like
storage format. It is easier to make bugs and let the code logic ugly. I
wonder do we still insist on this ,since we are designing the metadata
system with DRILL-6552.
Traditionally, people is used to design its table schema firstly before
firing a SQL query. I don't think this saves people too much time. Other
system like Spark is popular not due to lack the schema claiming. I think
we should be brave enough to take the right decision whether to still
insist on this feature which seems not so important but a burden.
Thanks.
