This talk will run through the list of filters that are shipped with HBase and show how they are used from a client application. Filters expose varying feature sets, but also exhibit an equally varying impact on read performance – but neither are directly intuitive. A skilled HBase practitioner should know how to select the proper filter for a given use-case, or how to combine sets of filters to achieve what is needed. The talk will conclude with an example for a custom filter and explain how to deploy it on a cluster.
