We would like to talk about disaggregated coordinator production rollout with some stats. Also we can inform community about changes needed to support deployment of disaggregated coordinator.
In the existing Presto architecture, single coordinator has become a bottleneck in a number of ways for cluster scalability. – With an increasing number of workers, the coordinator has the potential of slow down due to a high number of tasks. – In high QPS use cases, we have found workers can become starved of splits by excessive CPU being spend on task updates in coordinator. – Also with single coordinator, we have an upper limit on the worker pool because of above-mentioned reasons. To overcome with this challenges, we are coming up with a new architecture which supports multiple coordinators in a single cluster.
Presto is complicated with many intricacies. Ahana Cloud is the only managed service for Presto on AWS that simplifies Presto, bringing its power to platform teams of any size or skill set. In this session we’ll give you a quick overview of Ahana Cloud, including managing multiple Presto clusters seamlessly, querying a range of data sources, as well as just-released capabilities.
