--------------------------------------
Summary: Metastore (and other) Thrift APIs should use
request-response pattern
Key: HIVE-6061
URL: https://issues.apache.org/jira/browse/HIVE-6061
Project: Hive
Issue Type: Wish
Components: Metastore, Thrift API
Reporter: Sergey Shelukhin
Wish in lieu of "brainstorming" JIRA.
Metastore Thrift APIs currently use normal method signatures (e.g. int
foo(string bar, double baz)); this is problematic in Thrift because the APIs
cannot be evolved without breaking compat; and weird names have to be invented
because overloading is not supported either.
An easy solution to this is to have methods in the form of FooResponse
foo(FooRequest req); the structures can then be evolved easily.
This may apply also to other Thrift APIs, I have not checked.
This is a brainstorming JIRA for the transformations. Obviously this will
either double the API size, or cause massive backward incompatibility.
Maybe we can do 1-2 releases with both APIs, marking the old ones deprecated in
some form, and then remove them?
