Thank you very much. I will wait for the next lecture. By the way, thanks for the improved sound in the auditorium - questions and discussions were clearly understood.

There is a prior art for the German encoding: the representation of symlinks inside the fllesystem(well: some of them) . Symlinks are encoded INSIDE of the inode if there is enough space(the block numbers are vacant, anayway)

In 50:40, the slide says: "Payload contains full-string if it is 16-bytes or less." Should it be 12-bytes? Because the size field cannot be used for storing payload, there are only 12 bytes left for payload. I've read both Arrow's and DuckDB's implementation and they both inline strings of length less than or equal to 12.
