Tuning Solr and its Pipeline for Logs
This is an updated talk about how to use Solr for logs and other time-series data, like metrics and social media. In 2016, Solr, its ecosystem, and the operating systems it runs on have evolved quite a lot, so we can now show new techniques to scale and new knobs to tune.

We'll start by looking at how to scale SolrCloud through a hybrid approach using a combination of time- and size-based indices, and also how to divide the cluster in tiers in order to handle the potentially spiky load in real-time. Then, we'll look at tuning individual nodes. We'll cover everything from commits, buffers, merge policies and doc values to OS settings like disk scheduler, SSD caching, and huge pages.

Finally, we'll take a look at the pipeline of getting the logs to Solr and how to make it fast and reliable: where should buffers live, which protocols to use, where should the heavy processing be done (like parsing unstructured data), and which tools from the ecosystem can help.
