Hardware requirements for Presto
Most people are running Trino (formerly PrestoSQL) on the Hadoop nodes they already have. At Facebook we typically run Presto on a few nodes within the Hadoop cluster to spread out the network load. Generally, I'd go with the industry standard ratios for a new cluster: 2 cores and 2-4 gig of memory for each disk, with 10 gigabit networking if you can afford it. After you have a few machines (4+),

" At Facebook / We run our JVMs with a 16 gigabyte heap to leave most memory available for OS buffers / On the machines we run Presto we don't run MapReduce tasks / Most of the Presto machines we are on have 16 real cores and we use processor affinity to limit Presto to 12 cores "

" I found Dell to be the best mix of price, reliability, configurability, and maintainability. The Supermicro had 4 nodes in a 2U chasis. Each node had dual quad core processors and 3 3.5" 1 TB drives. The Dell had dual hex core processors and 12 2 TB SATA drives. / I bonded two gig-e nics per box."

Hadoop Hardware @Twitter: Size does matter!
At Twitter we started out with a large monolithic cluster that served most of the use-cases. As the usage expanded and the cluster grew accordingly, we realized we needed to split the cluster by access pattern. This allows us to tune the access policy, SLA, and configuration for each cluster. We will explain our various use-cases, their performance requirements, and operational considerations and
