bigdata (R)

otis — Tue, 15 Dec 2009 11:21:00 -0500

Bigdata(R) is an open-source scale-out storage and computing fabric supporting optional transactions, very high concurrency, and very high aggregate IO rates. Bigdata was designed from the ground up as a distributed database architecture optimized for very high aggregate IO rates running over clusters of 100s to 1000s of machines, but can also run in a single-server mode. Bigdata offers a distributed file system, similar to the Google File System but also useful for workflow queues, a data extensible sparse row store, similar to Googles widely recognized bigtable project, and map/reduce processing for parallelizing data intensive workflows over a cluster. Bigdata(R) comes packaged with a very high-performance RDF store supporting RDF(S) and OWL Lite inference. The Bigdata RDF Store is currently the only RDF database capable of operating distributed on a cluster with dynamic key-range partitioning of indices. The Bigdata RDF Store was designed specifically to meet requirements for very large scale semantic alignment and federation. RDF is a Semantic Web technology particularly well-suited to modeling graph-shaped data and metadata, such as an associative entity-link model, whereby actors are linked to one another in an ad-hoc fashion within the context of an evolving ontology of concepts for entity types and link types related to a particular problem domain. The Bigdata RDF Store is used operationally in data harvesting systems to create mash-ups of structured, semi-structured, and unstructured data from myriad sources in a schema-flexible manner.

Firewater Home Page

otis — Fri, 11 Dec 2009 04:55:00 -0500

Firewater is an open source scaleout RDBMS based on column store technology. It allows a cluster of commodity servers or virtualized cloud nodes to be used for fast response times on SQL and OLAP queries over massive datasets. It can also be used to parallelize execution even on a single multi-core node. Tagged by otis under olap, database, data warehouse, scalability, cluster, distribute,

nmdb - A multiprotocol network database

otis — Tue, 26 May 2009 02:52:00 -0400

nmdb is a network database (dbm-style) for controlled networks that can use different protocols to to communicate with its clients. It supports TIPC, TCP, UDP and SCTP. It consists of an in-memory cache that saves (key, value) pairs, and a persistent backend that stores the pairs on disk. Both work combined, but the use of the backend is optional, so you can use the server only for cache queries, pretty much like memcached.

Redis is a key-value database. It is similar to memcached but the dataset is not volatile, and values can be strings, exactly like in memcached, but also lists and sets with atomic operations to push/pop elements. Tagged by otis under keys, values, database, hash table, server, api,

Tokyo Tyrant: network interface of Tokyo Cabinet

otis — Tue, 26 May 2009 12:37:00 -0400

Tokyo Tyrant is a package of network interface to the DBM called Tokyo Cabinet. Though the DBM has high performance, you might bother in case that multiple processes share the same database, or remote processes access the database. Thus, Tokyo Tyrant is provided for concurrent and remote connections to Tokyo Cabinet. It is composed of the server process managing a database and its access library for client applications.

SpotSigs: Robust and Efficient Near Duplicate Detection in Large Web Collections - Stanford InfoLab Publication Server

otis — Mon, 22 Dec 2008 04:28:00 -0500

The contributions of SpotSigs are twofold: 1) by combining stopword antecedents with short chains of adjacent content terms, we create robust document signatures with a natural ability to filter out noisy components of Web pages that would otherwise distract pure n-gram-based approaches such as Shingling; 2) we provide an exact and efficient, self- tuning matching algorithm that exploits a novel combination of collection partitioning and inverted index pruning for high-dimensional similarity search.
