On-Demand Recordings from PrestoCon’s, Webinars, Meetups, and more
In this talk we are going to introduce Presto cross environment query federation which will enable query execution across different clouds and on-prem Presto clusters. This helps in reducing the network data transfer which results in lower Egress and Ingress costs when we are querying across clouds.
Presto on elastic capacity – Elasticity of a shared fleet is one of the fundamental pillars of the IaaS (Infrastructure-as-a-Service) world. The ability of services to efficiently use both guaranteed and non-guaranteed (opportunistic) capacity is important in such a setting. Presto is great when it runs on guaranteed capacity (i.e, capacity that is fixed and stable). But what if we want Presto to leverage elastic (opportunistic) capacity, i.e, capacity that is shifting, but in a predictable manner (think Amazon EC2 Spot Blocks)? In this lightning presentation, Neerad Somanchi and Abhisek Saikia will talk about how a recent feature developed for Presto can help it efficiently utilize such elastic compute.
