I have taken general Redis lectures, but this was my first theoretical lecture. To conclude, I am very satisfied. The lectures I have taken so far were lectures that showed the latency level according to simple commands, so they were very easy to learn and use, but this lecture explained in detail what problems can occur based on this information, in what situations it can be used effectively, and what functions should be used when developing. In addition, I think it was a good lecture that covered the differences between each architecture and development terms. I am still preparing for employment, but while doing various internships, I only knew how to use Redis in basic terms, and I did not delve into this much detail, but thanks to this good lecture, I learned a lot. :)
