  • Low Latency 'OLAP' with Hadoop and HBase

    by Andrei Dragomir

    We use “SaasBase Analytics” to incrementally process large heterogeneous data sets into pre-aggregated, indexed views, stored in HBase to be queried in realtime. The requirement we started from was to get large amounts of data available in near realtime (minutes) to large amounts of users for large amounts of (different) queries that take milliseconds to execute. This set our problem apart from classical solutions such as Hive and PIG. In this talk I`ll go through the design of the solution and the strategies (and hacks) to achieve low latency and scalability from theoretical model to the entire process of ETL to warehousing and queries.
