Velociraptor – The Next Generation of RaptorX – Vladimir Rodionov, Carrot Cache
Vladimir Rodionov, founder of Carrot Cache will present the Velociraptor – the next evolution of PrestoDB hierarchical caching framework RaptorX. Velociraptor enables efficient data and meta-data caching well beyond RaptorX limits in terms of number of data files (multi-billions), number of table partitions (multi-millions) and number of table columns (multi-thousands). Velociraptor replaces all five RaptorX caches (Hive meta-data, file list, query result fragments, ORC/Parquet meta-data and data I/O) with a scalable solution, based on Carrot Cache, which does not pollute JVM heap memory, does not affect Java Garbage Collector, keeps all data and meta-data off Java heap memory or on disk and can scale well beyond server’s physical RAM limit. Velociraptor supports server restart, by quickly saving and loading data to/from disk for automatic cache warm up.
Building a Modern Data Platform with Presto – Denis Krivenko, Platform24
Hadoop era is gone. Cloud computing is today’s reality. But… What if you cannot use public clouds? What if your cloud does not provide data platform capabilities? What if you want your solution to be cloud agnostic? In this case you create your own cloud native data platform on Kubernetes. In the session Denis will talk about reasons for building analytics data platform solution in Platform24, cloud native data platform architecture principles, data stack they use and why Presto plays one of the key roles in it.
