  • Patent number: 10528590
    Abstract: Techniques for optimizing a query with an extrema function are provided. In main memory, a data summary is maintained for a plurality of extents stored by at least one storage server. The data summary includes an extent minimum value and an extent maximum value for one or more columns. A storage server request is received, from a database server, based on a query with an extrema function applied to a particular column of a particular table. The data summaries for a set of relevant extents are processed by maintaining at least one global extrema value corresponding to the extrema function and, for each relevant extent of the set of relevant extents, determining whether to scan records of the relevant extent based on at least one of the global extrema value and an extent summary value of the data summary of the relevant extent.

  • Patent number: 10521398
    Abstract: A technique for facilitating file system operations in a data storage system provides multiple version family databases. Each version family database identifies members of a respective version family, i.e., a respective set of files in a file system that are related by file snapping. When a snap of a file is created, the file system updates a version family database for the version family that includes the file, such that the version family database identifies both the file and the snap.

  • Patent number: 10503697
    Abstract: A small file storage system reduces the cost of storing and reading segmented data in a deduplication storage system. A data-blocking scheme is used to store small files instead of generating different levels of metadata as is done for larger files in deduplication systems. Among other advantages, the data blocking scheme reduces the cost of reading metadata segments from the content store, reduces the cost of index lookup, CM region read and decompression, and the cost of recalling and restoring small files from cloud storage, all of which contribute to better read performance. Other advantages include faster verification of small files, and improvements in small file data locality on disk with larger segment sizes. By eliminating the need to update metadata segments, embodiments of the small file storage system advantageously increase the efficiency of file updates, especially since updates to smaller files are more random in nature.

  • Patent number: 10489374
    Abstract: A method includes setting, by an update processor, a write latch in a first data structure associated with an object. The first data structure is copied to a storage structure. A history tuple sequence number (TSN) of the first data structure is set to point to a TSN of the copied first data structure. The version identifier is set to point to a transaction identification for the object. Data portions are updated for the first data structure. The version identifier is read from the first data structure. It is determined whether the version identifier of the first data structure is visible for a transaction including isolation requirements. If version identifier of the first data structure is visible, the first data structure is accessed and it is determined whether the version identifier of the first data structure changed since starting the transaction.
