    Cross-Site BigTable using HBase
    • Monday, May 05 2014
    • Category: HBaseCon, Presentation Slides
    As HBase continues to expand in application and enterprise or government deployments, there is a growing demand for storing data across geographically distributed datacenters for improved availability and disaster recovery.

    Real-time HBase: Lessons from the Cloud
    • Monday, May 05 2014
    • Category: Presentation Slides, HBaseCon
    Running HBase in real time in the cloud provides an interesting and ever-changing set of challenges -- instance types are not ideal, neighbors can degrade your performance, and instances can randomly die in unanticipated ways. This talk will cover what HubSpot has learned about running in production on Amazon EC2, how to handle DR and redundancy, and the tooling the team has found to be the most helpful.

    HBase Read High Availability Using Timeline-Consistent Region Replicas
    • Monday, May 05 2014
    • Category: HBaseCon, Video, Presentation
    HBase has ACID semantics within a row that make it a perfect candidate for a lot of real-time serving workloads. However, single homing a region to a server implies some periods of unavailability for the regions after a server crash. Although the mean time to recovery has improved a lot recently, for some use cases, it is still preferable to do possibly stale reads while the region is recovering. In this talk, you will get an overview of our design and implementation of region replicas in HBase, which provide timeline-consistent reads even when the primary region is unavailable or busy.

    From MongoDB to HBase in Six Easy Months
    • Monday, May 05 2014
    • Category: Presentation Slides, HBaseCon
    Pushing well past MongoDB's limits (2TB data every week) is an interesting exercise in operational frustration. It also severely hampers flexibility of design for new use cases. This talk covers the architectural journey from MongoDB/Redis to HBase at Optimizely -- including the performance, design flexibility, speed of implementation, and other gains made. It also covers the operational setup needed to monitor and maintain the system as well as lessons learned from the migration process itself.

    Tales from the Cloudera Field
    • Monday, May 05 2014
    • Category: Presentation Slides, HBaseCon
    From supporting the 0.90.x, 0.92, 0.94, and 0.96 HBase installations on clusters ranging from tens to hundreds of nodes, Cloudera has seen it all. Having automated the upgrade paths from the different Apache releases, we have developed a smooth path that can help the community with upcoming upgrades. In addition to automation best practices, in this talk you'll also learn proactive configuration tweaks and operational best practices to keep your HBase cluster always up and running. We'll also walk through how to contain an application bug let loose in production, to minimize the impact on HBase posed by faulty hardware, and the direct correlation between inefficient schema design and HBase performance.

    Bulk Loading in the Wild: Ingesting the World's Energy Data
    • Monday, May 05 2014
    • Category: CDH, Presentation, Video
    HBase is designed to store your big data and provide low latency random access to that data. One of its most compelling features is Bulk Loading, which enables the generation of HFiles that can then be passed to the RegionServers. Opower's energy insights platform uses it to ingest the hundreds of millions of meter reads it receives daily from its partner utility companies. This presentation will walk you through the HBase Bulk Loading process and Opower's adoption of it as an important piece of its HBase ecosystem.
