I have a regular Bash shell history with about 750 000 entries on an SSD on a modern laptop, and would take about 1 second for Bash to load 1 million entries. The startup delay and the memory usage is noticeable.
Storing the shell command history in a database instead of the memory of each interactive Bash shell, it would make Bash start up faster, and also use less memory.
