Where to get a lot of data for processing?

Question

IT education

Good afternoon.
Have some knowledge of algorithms and data structures. I want to delve into this topic: pull up the theory and try it in practice. The question arose, where can one get large enough amounts of data to experiment with them?
There was an idea to pump out historical indicators on stock indicators, but there the data is rather monotonous. What data can be found in the public domain? The only thing that comes to the goloka is the data of the meteorological center.

Write yourself a data generator. This will only deepen your knowledge of algorithms and data structures + open up a wide field for any experiments.
