Advanced Amazon Redshift: Table Layout and Schema DesignGo to Lab
The lab was great fun, but it is a little out of date. The compression data sizes didn't match the lab contents, but tended to follow the pattern.
When I am in RDP, it says the connection fails. I can't go beyond that point
I can understand how to affect type difference into a performance
I think the content needs to be revised. ZSTD versus LZO encoding Redshift is improving ... and this course is now outdated! Also the last part the outcome v4 vs v5 v4 is better and faster... . I think a bit of refund is needed on this..
the COPY commands took too long - I felt pressed for time.
not very clear difference between table 3 and 4. also for table 3 it says that redshift recommends keys but i don't see where is that recommendation
