Patch Set 2:

(7 comments)

Thanks! This is great.

I didn't look as closely as I did in revision 1, but I'll check again tomorrow and but can
probably give a +1. I'll see if anyone wants to take a look at the python code. Otherwise
I'll give it a +2 after I look again.

PS2, Line 9: lease
release
... though I guess it seems odd to _re_ lease the Impala Kudu integration which has never
been leased before (at least not GA).


PS2, Line 10: 5.10
2.8


PS2, Line 9: In preparation for the public lease of Kudu integration in
           : 5.10, we need to make sure that we've covered as much of the
           : Kudu related functionality with tests as possible. This patch
           : covers UPSERT.
Not really needed in the commit.


PS2, Line 14: It also introduces a new test section 'DML_RESULTS', which
            : takes the name of a table as a comment and the contents of the
            : table as its body and then verifies that the body matches the
            : actual contents of the table. This makes it easy to check that a
            : DML operation has the desired effect on the contents of a table,
            : rather than always having to add another test case that runs a
            : select on the table.
nice

That's great, I didn't know it existed.

Ah, makes sense. Thanks for looking into that, I think it's fine. We can think about changing
the wording in the future (not something to pile on now).

might be good to put a limit on here for safety, e.g. the number of rows specified in the
"expected rows" section, or even just some big constant like 1000. Even if it's kinda hacky/random,
it'd be crazy to have a test case where the DML_RESULTS section even got close but would prevent
the test from trying to do something dumb.
