The Hadoop Online Prototype (HOP) is a modified version of Hadoop MapReduce that allows data to be pipelined between tasks and between jobs. This can enable better cluster utilization and increased parallelism, and allows new functionality: online aggregation (approximate answers as a job runs), and stream processing (MapReduce jobs that run continuously, processing new data as it arrives).

DERI Pipes: Open Source, Extendable, Embeddable Web Data Mashups

otis — Tue, 15 Dec 2009 12:38:00 -0500

DERI Pipes: Open Source, Extendable, Embeddable Web Data Mashups Inspired by Yahoo's Pipes, DERI Pipes is an engine and graphical environment for general Web Data transformations and Mashup. Pipes, in general, produce as an output streams of data (e.g. XML, RDF,JSON) that can be used by applications. However, when invoked by a normal browser, they provide a end user GUI for the user to enter parameter values and browse the results (see the examples below) .

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.
