Mathematically speaking indexes reduce searches by a logarithmic factor. Logs grow very slowly especially for large numbers. For example, the log base 10 of million is 6.

Wow! in one video you teach how to use a data generator, how to use a database, create a cursor, an index and how to measure time, !
Only a question, how many indexes can be supported by a database until the access time collapsed?
Thank you!

But what if a new record was added after indexing?
Would it combine the search results from the index and the remaining data or just skip non-indexed stuff ?

Appreciate your tutorial! Immediately actionable advice for a work project 🎉

Please post a github gist or link to a repo for your demo code. Didn't find this video in vidstream or youtube-tutorials
