High density time-series data indexing and compression
Time-series columnar-based information is received and indexed in a compute infrastructure for cost-effective cloud-based object storage. The approach leverages a file format that enables highly-performant search and retrieval of the data stored in the cloud. In operation, an indexer receives the time-series information, indexes that information according to the file format, and forwards the indexed information for storage to the object store, where it is stored as a set of time-based partitions. A partition comprises a set of files, namely, a manifest file, a data file, and an index file. These files are structured as a compact instance of a set of raw unstructured data that comprises the given partition. Highly-performant information retrieval is enabled in response to a time-bounded query, because operations at a query peer (with respect to one or more partitions) are carried out in real-time during query processing and without requiring retrieval of the data file as a whole. |

Partitioning a distributed filesystem namespace
The described technology is generally directed towards domains that data services can use to collect files of a global filesystem namespace into groups.

Thereafter, the data service can use the domain membership information associated with a file to determine whether to include that file in a data service operation. In one implementation the membership information is maintained in file metadata, facilitating fast and efficient retrieval of the information in near constant time. Exclusion from a domain, hard links, renames and alternate data streams are among the various aspects supported by the domain technology. |

Yawing buoy mast for floating offshore wind turbines
The present invention provides a novel, floating, offshore wind turbine (FOWT) structure, referred to as a yawing buoy mast (YBM) structure. The YBM platform vertically combines a submerged spar buoy with outrigger legs and a mast on which a wind turbine nacelle is mounted. Compared to a conventional spar buoy wind turbine, weight is significantly reduced by optimizing how loads are borne and reacted by the floating structure. The mass of the YBM platform is reduced relative to the energy captured by the turbine resulting in a reduction in the cost of energy (COE). Platform load dynamics are coupled with the dynamics of the wind turbine by integration of the YBM platform and turbine controllers. |
