Subject [jira] Commented: (HIVE-1464) improve test query performance
Date Wed, 21 Jul 2010 01:45:52 GMT


John Sichi commented on HIVE-1464:

No additional comments from me except that I am looking forward to faster tests!  :)

For Eigenbase, what we do is to have a set of fixture objects which tests are not supposed
to mess with, and we have an automatic cleanup at the beginning of each test case which drops
anything in the catalog other than fixture objects.  That allows us to avoid all those DROP
TABLES at the beginning and ending of each test (and allows DROP TABLE to fail as it should
when the object doesn't exist).

Joy's approach takes us most of the way there.

> one major problem seems to be that all the test warehouse tables are deleted and created/re-populated
for each test. most of the times this is not required and if we can fix this the tests will
run much faster.
