At PrestoCon Day 2023, we had a fantastic panel discussion with speakers from Meta, Uber, and Intuit. Each shared their experiences and use cases of scaling Presto in their respective companies. Let’s take a look at the key points discussed by each panelist, including use cases, key metrics, and future plans for Presto. Sign up…
Raptor is a Presto connector (presto-raptor) that is used to power some critical interactive query workloads in Meta (previously Facebook). Though referred to in the ICDE 2019 paper Presto: SQL on Everything, it remains somewhat mysterious to many Presto users because there is no available documentation for this feature. This article will shed some light…
RaptorX is an internal project name aiming to boost query latency significantly beyond what vanilla Presto is capable of. This blog post introduces the hierarchical cache work, which is the key building block for RaptorX. With the support of the cache, we are able to boost query performance by 10X. This new architecture can beat…
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. We…
