Abstract: Techniques are provided for implementing garbage collection and bin synchronization for a distributed storage architecture of worker nodes managing distributed storage composed of bins of blocks. As the distributed storage architecture scales out to accommodate more storage and worker nodes, garbage collection used to free unused blocks becomes unmanageable and slow. Accordingly garbage collection is improved by utilizing heuristics to dynamically speed up or down garbage collection and set sizes for subsets of a bin to process instead of the entire bin. This ensures that garbage collection does not use stale information about what blocks are in-use, and ensures garbage collection does not unduly impact client I/O processing or conversely falls behind on garbage collection. Garbage collection can be incorporated into a bin sync process to improve the efficiency of the bin sync process so that unused blocks are not needlessly copied by the bin sync process.

Abstract: A comprehensive utilization method of beneficiation-metallurgy-chemical combination for germanium-rich lignite includes the following steps: 1) germanium-rich lignite sizing and grinding, 2) catalytic pre-oxidation, 3) nitric acid leaching, and 4) recycling and enrichment of germanium solution. The high effective extraction of germanium from the germanium-rich lignite was achieved via a combination of mineral beneficiation, hydrometallurgy, and chemical processing. Meanwhile, a high yield and high degree of depolymerization humic acid product was produced as byproducts. This method could not only effectively avoid high carbon emission and organic resource waste during conventional germanium-rich lignite pyrometallurgical processing, but also could produce humic acid as quality raw materials for metallurgical and agricultural industries, which has advantages of less environmental pollution, high extraction efficiency, and low comprehensive costs.
