Abstract: A method for rapid data analysis includes receiving and interpreting a first query operating on a first dataset partitioned into shards by a first field; collecting a first data sample from a first set of data shards; calculating a first result to the first query based on analysis of the first data sample; and partitioning a second dataset into shards by a second field based on the first result.

Abstract: Aspects of the present disclosure control aging of a signal path in an idle mode to mitigate aging. In one example, an input of the signal path is alternately parked low and high over multiple idle periods to balance the aging of devices (e.g., transistors) in the signal path. In another example, a clock signal (e.g., a clock signal with a low frequency) is input to the signal path during idle periods to balance the aging of devices (e.g., transistors) in the signal path. In another example, the input of the signal path is parked high or low during each idle period based on an aging pattern.

Abstract: A method for clock switching includes propagating a first clock signal through a first clock path, propagating a second clock signal through a second clock path, generating a first delay control signal based on the first clock signal, and generating a second delay control signal based on the second clock signal.

The method also includes, in a second mode, coupling the second clock path to the delay circuit and inputting the second delay control signal to the control input of the delay circuit.
