Hello Marton Greber, Attila Bukor, Kudu Jenkins, Wenzhe Zhou,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/20226
to look at the new patch set (#2).
Change subject: KUDU-1945 Add Python example for non-unique PK
......................................................................
KUDU-1945 Add Python example for non-unique PK
In commit 3019848d00ac721b30d98a1aeb77bc205352b7b5 a C++ client example
has been added to showcase the usage of the non-unique PK. This patch
translates this particular example to Python.
The C++ examples are tested during upstream submission, however the Java
and Python client examples are not tested automatically. Therefore,
I did manual testing and created a ticket to track this improvement:
KUDU-3478.
Manual testing has been done using the following configurations:
Ubuntu 18.04 x86_64: Python2.7
Ubuntu 18.04 x86_64: Python3.7
macOS Monterey M1(arm64): Python3.7
(I couldn't setup the Python2.7 interpreter properly on my mac)
STDOUT of the example:
kudu.Schema {
non_unique_key int32 NOT NULL
auto_incrementing_id int64 NOT NULL
int_val int32 NOT NULL
PRIMARY KEY (non_unique_key, auto_incrementing_id)
}
