  • Why HBase? Or How I learned to stop worrying and love consistency

    by Shaneal Manek

    There are a number of excellent databases that have proven invaluable when working with `big data` – including Cassandra, Riak, DynamoDB, MongoDB, and HBase. So, how do you decide which is the right solution for you? This talk will start by briefly discussing some of the theory involved with distributed databases – from the oft-cited (and almost-as-often misunderstood) CAP theorem, to vector clocks and the difficulties of eventual consistency, and much more. We will then compare how mainstream distributed databases make use of these concepts, and the tradeoffs they incur. Unfortunately, due to the nature of these tradeoffs, there is no one-size-fits all solution. So, we`ll discuss what classes of problems each of these systems is appropriate for – and include some real world benchmarks – to help you make an informed decisions about your distributed systems.

    At 2:25pm to 3:05pm, Wednesday 13th June
