The document discusses leveraging Alluxio with Spark SQL to speed up ad-hoc analysis. Alluxio is used to improve I/O efficiency for a data infrastructure with over 30PB of data and 70TB of incremental data daily. The organization explored using Alluxio with Spark SQL for ad-hoc queries and found it could provide 3-5x performance acceleration for large datasets, while not degrading performance for small datasets. Future work includes fully deploying Alluxio for ad-hoc queries and applying it to other frameworks.
