Abstract: A system and machine-implemented method for sorting Next-Generation Sequencing (NGS) reads in O(n) time and space complexity that makes use low sparsity and nearly uniform distribution of the input array. The genome position field in the input array is used to determine the target position of the output array. Duplicate target positions due to n-fold coverage are handled by assigning either overflow buckets to each position or anterior assigning multiple target slots in the output array for each genome position depending on the distribution of reads over the genome and the resulting probability of hitting an already occupied slot. Once every tuple in the input array has been written to the output array, the output array in read through ascending order and each tuple is appended to the end of a final result array.

Abstract: 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.

Abstract: Techniques are provided for moving data between partitions. Such a process may be performed without requiring any locks that block transactions that target a partition from being executed. Instead, such transactions may proceed while a move operation is being performed. The move operation involves copying data from the targeted partition to another partition that is hidden from (or “invisible” to) those transactions that attempt to read from or write to the partition. During the move operation, changes that are made to the partition are also reflected in a journal. Eventually, the changes reflected in the journal are drained and applied to the hidden partition. Once the partition and the hidden partition are synchronized, the identities of the partitions are swapped so that future transactions will target the previously-hidden partition instead of the previously-viewable partition.
