  • Publication number: 20200004311
    Abstract: A system is disclosed that provides emergency backup power to a solid-state drive (SSD) that may not contain any internal supercapacitors. The SSD may include a first connector and a hold-up power supply. The first connector may have a predetermined form factor and may being capable of being connected to a corresponding connector of a midplane of a storage system. The first connector may include a main power connection that is connected to a main power supply of the midplane if the first connector is connected to the corresponding connector of the midplane. The hold-up power supply may be internal to the SSD, and may receive hold-up energy from an external energy source for a predetermined amount of time after the first connector has been disconnected from the main power connection of the midplane so that the SSD may store any host data write requests that the SSD has acknowledged.

  • Publication number: 20190384844
    Abstract: Systems, methods, and computer-executable instructions for creating a query execution plan for a query of a database includes receiving, from the database, a set of previously executed query execution plans for the query. Each previously-executed query execution plans includes subplans. Each subplan indicates a tree of physical operators. Physical operators that executed in the set of previously-executed query execution plans are determined. For each physical operator, an execution cost based is determined. Invalid physical operators from the previously-executed query execution plans that are invalid for the database are removed. Equivalent subplans from the previously-executed query execution plans are identified based on physical properties and logical expressions of the subplans. A constrained search space is created based on the equivalent subplans. A query execution plan for the query is constructed from the constrained search space based on the execution cost.
