Omid: Transactional Support for HBase

The support for transactions is an essential part of a database management system (DBMS). Without this support, the developers are burdened with ensuring atomic execution of a transaction despite failures as well as concurrent accesses to the database by other transactions. We term the systems that lack this feature data store (rather than DBMS). Examples are HBase, BigTable, PNUTS, and Cassandra. In this talk, I present Omid, our open source tool for transactional support on top of HBase (https://github.com/yahoo/omid). Benefiting from a centralized client-replicated status oracle (CrSO), Omid (i) avoids distributed locks., (ii) scales up to 60,000 TPS and a thousand clients, (iii) requires no change into HBase, and (vi) adds a negligible overhead on data servers.

Apache Bigtop: the first ever 100% Apache Bigdata management distribution and so much more.

Over the past couple of months Apache Bigtop (incubating) has emerged not only as the definitive100% Apache Bigdata management distribution, but also as a framework that helps Hadoop andvarious Apache Bigdata management projects deliver quality releases on time, without worryingtoo much about intricacies of package management and idiosyncrasies of various Linux distributions.The goal of Apache Bigtop is to provide a stable platform for packaging, validating and deployingall of the Apache Bigdata projects. In that, Bigtop is quickly becoming the Debian of various Hadoopdistributions with companies like Cloudera, Canonical, EMC and EBay using its infrastructure forbuilding solutions of their own.

Presenter: Roman Shaposhnik, Apache Bigtop

Apache HBase: Project Update

Catch up on the lastest happenings over in Apache HBase. We'll reviewthe new features that ship in the just released HBase[masked] andinteresting near-horizon developments.
