This is a guest blog by Ashwin Sinha with an original blog source. This blog introduces Wormhole— open source Dockerized solution for deploying Presto & Alluxio clusters for blazing fast analytics on file system (we use S3, GCS, OSS). When it comes to analytics, generally people are hands-on in writing SQL queries and love to analyse data which resides in a warehouse (e.g. MySQL database). But as data grows, these … Continued

This tutorial guides users to set up a stack of Presto, Alluxio and Hive Metastore on your local server, and it demonstrates how to use Alluxio as the caching layer for Presto queries.
Alluxio clusters act as a data access accelerator for remote data in connected storage systems. Temporarily storing data in memory, or other media near compute, accelerates access and provides local performance from remote storage. This capability is even more critical with the movement of compute applications to the cloud and data being located in object stores separate from compute. Caching is transparent to users, using read/write buffering to maintain continuity with persistent storage. Intelligent cache management utilizes configurable policies for efficient data placement and supports tiered storage for both memory and disk (SSD/HDD).
