Data-Center Replication with Apache Accumulo - Josh Elser

Apache Accumulo presently lacks the ability to automatically replicate its contents to another Accumulo instance with low latency. The only options currently available involve quiescing a table, exporting that table, copying it to the remote instance and importing it. This is unacceptable for a few reasons, the most important of these reasons being the require unavailability to export the given table. This talk will outline the problems in designing a low-latency replication system for Accumulo tables, describe an implementation that leverages some useful features of Accumulo, and outlines future work in the area.
