It used to be, for instance, that when you went shopping you’d have your stuff retrieved for you by a small army of clerks running around the shop; indeed that’s still how it’s done in places like India with an abundance of cheap labor. But humans were getting expensive in the 1950s and ‘60s, so everyone wanted to reduce the human component, and so in that period you saw the rise of supermarkets and discount stores, where the whole innovation is getting the stuff yourself. (Sam Walton’s Made in America is a good record of what that revolution was like from the inside; consumers tended to be quite happy with the whole thing, since corporate savings could be passed on in the form of cheaper goods.) And it’s the same reason why in the ‘50s and ‘60s you saw the rise of laundromats, vending machines, self-service gas stations, and “fast food” restaurants like McDonald’s.，这一点在超级权重中也有详细论述
When data is inserted into ClickHouse, it creates one or more blocks (parts). In replicated environments, such as ClickHouse Cloud, a hash is also written in ClickHouse Keeper. Subsequent inserted blocks are compared against these hashes and ignored if a match is present. This is useful since it allows clients to safely retry inserts in the event of no acknowledgement from ClickHouse e.g., because of a network interruption. This requires blocks to be identical i.e., the same size with the same rows in the same order. These hashes are stored for only the most recent 100 blocks, although this can be modified. Note higher values will slow down inserts due to the need for more comparisons.
