The Facebook Presto team has been collaborating with Alluxio on an open source data caching solution for Presto.
This is required for multiple Facebook use-cases to improve query latency for queries that scan data from remote sources such as HDFS.
We have observed significant improvements in query latencies and IO scans in our experiments.
