Abstract: Embodiments are directed to tiered data store with persistent layers. A write tier in the file system for storing in a file system. A value for a performance metric that corresponds to write requests to the file system may be predicted based on characteristics of the write requests such that the performance metric may be determined based on a plurality of interactions with the write tier. The predicted value that exceeds a threshold value of the performance metric may be employed to cause performance of further actions, including: queuing a portion of the write requests in a memory buffer based on the predicted value and the threshold value; combining the queued portion of the write requests into s; storing the data segments in the write tier such that a measured value of the performance metric may be less than the threshold value.

Abstract: An illustrative example embodiment of a device that facilitates installing at least one elevator door component, includes a detector that is configured to detect at least one reference feature in a vicinity of a desired position of the elevator door component. A processor is configured to use information from the detector to determine the desired position of the elevator door component relative to the at least one detected feature. An indicator is configured to provide at least one indication corresponding to the desired position of the elevator door component.

Abstract: Disclosed is an elevator system having: a door panel configured for moving along a first axis for opening and closing of the door panel at an entryway, the door panel having a door magnet, the entryway including a sill, the sill having a sill magnet, wherein the door magnet and the sill magnet are configured for forming a first magnetic pairing, and wherein the first magnetic pairing guides the door panel to move along the first axis and prevents the door panel from moving in a lateral direction with respect to the first axis.
