Feedback - Table in step 6 of Data Modelling notebook has a data mismatch

table in Step 6 of Cassandra Developer Workshop #4 - Data Modelling need clarity/update

Table in Step 6 of Cassandra Developer Workshop #4 - Data Modelling (notebook) seems to have incorrect mapping for userids (6666666-6666-6666-6666-666666666666, 77777777-7777-7777-7777-777777777777) . These are mapped to av@datastax.com , ah@datastax.com respectively. It is supposed to be in reverse. Please check. This leads to little confusion.

This was an issue previously. I fixed it right after the week 2 workshop so you should not be seeing any discrepancy now as @Erick Ramirez posted. Curious if you re-download the notebook @amudha.motcham_193135 if you still see this? I wonder if you grabbed this version before I made the fix.

Thanks! That would explain it. :)

Thanks for the feedback and thanks for attending the workshop!

I've got the Data Modelling notebook (DataModel.tar) from the week 2 workshop and this is the table I can see in step 6:

The queries in the cell to me looks like they match the table:

INSERT INTO killrvideo.user_credentials (userid, email, password)
  VALUES(66666666-6666-6666-6666-666666666666, 'ah@datastax.com', 'C@ss@ndr@43v3r');
INSERT INTO killrvideo.user_credentials (userid, email, password)
  VALUES(77777777-7777-7777-7777-777777777777, 'av@datastax.com', 'C@ss@ndr@3v3rywh3r3');

Perhaps I'm not looking in the right spot. If you could tell me where the discrepancy is, we'd be happy to correct it. Cheers!
