Abstract: A storage manager implements adaptive snapshot chunk sizing, wherein snapshot chunks are sized differently based on an access pattern for volume data to be included in the respective snapshot chunks. For example, sequentially accessed sectors of a volume may be grouped into snapshot chunks of varying sizes and individually accessed sectors may be snapshotted as individual snapshot chunks. When a volume is populated from the snapshot chunks, the volume data is re-mapped into standard sized volume blocks. In some embodiments, an optimized manifest is generated indicting an order in which the snapshot chunks are to be used to populate a volume to perform a launch process using the volume. In some embodiments, adaptively sized snapshot chunks and a corresponding optimized manifest are used to accelerate performing a launch using a volume populated from a snapshot, such as launching an operating system, an application, a database, a machine image, etc.

Abstract: A passive, hydrodynamic technique implemented using a microfluidic device to perform co-encapsulation of samples in droplets and sorting of said droplets is described herein. The hydrodynamic technique utilizes laminar flows and high shear liquid-liquid interfaces at a microfluidic junction to encapsulate samples in the droplets. A sorting mechanism is implemented to separate sample droplets from empty droplets. This technique can achieve a one-one-one encapsulation efficiency of about 80% and can significantly improve the droplet sequencing and related applications in single cell genomics and proteomics.
