Two-stack sliding window aggregation covers any aggregation operation that satisfies associativity (sum, count, extrema, and more complex merges), and is not limited to the extrema-type queries that a monotonic queue can handle.

UnverifiedTwo-stack sliding window aggregation deals with the structural expiration problem of "the most recent N elements" and guarantees exact results, but it does not solve the problem of estimating quantiles in an extremely large window while saving memory; the two are often used together.75% similarUnverifiedWhen the window boundaries are more complex (such as weighted windows or multi-level windows) or the aggregation requires exact medians or quantiles, two-stack aggregation is no longer the optimal solution, and one must turn to specialized streaming algorithms such as t-digest and GK summary.73% similarUnverifiedThe evolution directions of the Kirin logic-folding chip include continuing to shrink the hybrid bonding pitch, adding interconnects, having more modules participate in folding, and exploring more layers and optimizing design tools.68% similar
