Subject [jira] [Commented] (HIVE-17990) Add Thrift and DB storage for Schema Registry objects
Date Fri, 08 Dec 2017 18:33:00 GMT


Peter Vary commented on HIVE-17990:

I might have misunderstood the intenet. I thought, that any table created in Hive will be
immediately readable through Schema Registry, and data stored with a Schema would be readable
from Hive, thus requiring all fields filled, and adding data. If this is not the case, then
you are right, this is not a valid issue.

If I understand the diagrams correctly, then in the final version we could access the column
information through the Schema objects only. Currently theoretically every partition can have
a different column set, so when we read the partitions of a table, we transfer these data
for all of the paritions again and again. If we add extra objects to this hierarchy, then
we end up transfering those multiple times too. I might missing here something too, so feel
free to correct me if I wrong.

Missed the tests - they have obvious name, so I do not know why :( Thanks for pointing them
