Deduplicating at query time can be achieved by grouping the data on the fields, which uniquely identify a row, and using the argMax function with a date field to identify the last value for other fields. ReplacingMergeTree allows rows with the same sorting key (ORDER BY key) to be deduplicated on merges. Note this is "best effort" only: sometimes parts will not be merged with the merge process scheduled at non-deterministic intervals. It, therefore, does not guarantee the absence of duplicates. Users can also utilize the FINAL modifier to force this deduplication at SELECT time. While FINAL does add overhead, it has received significant performance improvements in recent versions including multi-threaded processing, and is suitable for many production workloads.
We also confirmed that no critical secrets were at risk of being exposed.

All of this seems to point to a glum future where unfettered and dangerous AI proliferates. But the companies beg to differ. When I presented my bleak argument, they insisted that safety was as important as ever, despite the Pentagon’s affection for unreliable killer drones. “I don't think the race to the top is dead,” says Anthropic’s chief science officer Jared Kaplan, urging me to shift my gaze from the battlefield and the marketplace to the research labs. “There are a lot of researchers at every lab that care a lot about doing the right thing. They want to see their research used for the betterment of humanity, and I think there is competition not just to make them more useful or capable, but also safer,” he tells me.
，这一点在手游中也有详细论述
