Normalizing data for fast superscalar processing

08/20/15 - 20150234778 - A data normalization system is described herein that represents multiple data types that are common within database systems in a normalized form that can be processed uniformly to achieve faster processing of data on superscalar CPU architectures. The data normalization system includes changes to internal data representations of a database
Inventors: Aleksandras Surna, Erik Ismert, Srikumar Rangarajan, Nimish S. Khanolkar

Scalable index build techniques for column stores

07/09/15 - 20150193485 - Architecture that includes an index creation algorithm that utilizes available resources and dynamically adjusts to successfully scale with increased resources and be able to do so for any data distribution. The resources can be processing resources, memory, and/or input/output, for example. A finer level of granularity, called a segment, is
Inventors: Artem Oks, Qingqing Zhou, Srikumar Rangarajan, Richaraleksandras Surna, Wey Guy, Cipri Clinciu, Ashit Gosalia

On demand parallelism for columnstore index build

12/25/14 - 20140379725 - The degree of parallel processing used to build a database index can be dynamically adjusted based on actual memory usage of individual parallel processing units. Memory can be reserved to prevent an out-of-memory condition. A predetermined number of initial parallel processing units can be activated. The actual usage of resources

Adaptive row-batch processing of database data

09/22/11 - 20110231389 - Architecture that provides for greater interoperability between column stores and row stores by leveraging the advantages both have to offer. The architecture operates automatically (e.g., dynamically) to move between row oriented processing mode and batch processing mode, and the combination thereof, when it is more beneficial to run in one
Inventors: Aleksandras Surna, Per-ake Larson, Srikumar Rangarajan

Columnar storage of a database index

09/08/11 - 20110219020 - Methods, systems, and computer-readable media of columnar storage of a database index are disclosed. A particular columnar index includes a column store that stores rows of the columnar index in a column-wise fashion and a delta store that stores rows of the columnar index in a row-wise fashion. The column

Database mirroring

06/16/11 - 20110145201 - Methods, systems, and computer-readable media of database mirroring are disclosed. A particular method includes initiating a transaction that modifies one or more pages of a first database. Each page includes a structure modification operation (SMO) bit and initiating the transaction includes setting the SMO bit of each of the one
Inventors: Marcel Van Der Holst, Robin D. Dhamankar, Hanumantha R. Kodavalla, Srikumar Rangarajan

Optimized reverse key indexes

12/03/09 - 20090300013 - Aspects of the subject matter described herein relate to optimized reverse key indexes. In aspects, a dispersion function disperses index values such that they are distributed across multiple pages of an index. The dispersion function utilizes a dispersion factor that indicates to what extent the index values are dispersed. Because
Inventors: Hanumantha R. Kodavalla, Pravin Mittal, Srikumar Rangarajan

Efficient query processing of dml sql statements

07/30/09 - 20090193060 - Various technologies and techniques are disclosed for efficiently processing DML SQL statements through minimal logging and optimized insertions. Rows are inserted into a table in a database in a sorted order. When an insertion of a particular row into the table causes a page split and a new page created
