Redis [QUESTION] Why does redis need to observe whether the server is currently executing the two commands bgsave or bgrewriteaof when it expands the hash table?

Why does redis need to observe whether the server is currently executing the two commands bgsave or bgrewriteaof when it expands the hash table?

bgsave or bgrewriteaof, they both need to fork a child process to handle the work we rely on copy on write, so it is better not to do the rehash and mess up the memory
