The Baltimore ACM Chapter invites you to attend the following lecture

"Apache Accumulo: Extensions to Google's Bigtable Design"

When: 5:00 pm, Thursday, March 29
Where: Murphy Fine Arts Hall, Morgan State University

Speaker: Adam Fuchs, National Security Agency


Keeping up with new mission needs requires a highly adaptive
infrastructure to support hundreds of distinct analysis applications
and data, while supporting rapid, decentralized development of new
applications and new data types. In support of these requirements the
NSA Computer and Information Sciences Research Group is using open
source data cloud computing components, as well as contributing back
one of its own.

Apache Accumulo is a flexible, high performance distributed key/value
store based on the published Google Bigtable design and built on top
of Apache Hadoop. NSA has been developing Accumulo since 2008 and
released the source code in 2011. This talk will discuss the
motivations behind NSA's efforts as well as key design and performance
features of Accumulo, including cell-level access labels and

Cell-level labels provide expressive, fine-grained control over access
to data stored in Accumulo, which is essential in a national security
setting and may also be useful for organizations who face legal,
regulatory, or other data handling restrictions. Iterators are a
server-side programming mechanism that can modify key/value pairs at
various points in the data management process. They enable new design
patterns such as arbitrary aggregation and document-partitioned
indexing in Accumulo.

Admission is free and open to the public.

The talk will be preceded by refreshments and pizza at 4:30 pm.

RSVP: If you would like to attend, please email Glenn Speights at
