Don Bosco Durai who is the founding member of the project Apache Ranger will do a quick show and tell on how to do fine grain authorization using Apache Ranger in PrestoDB.
Apache Ranger has been the user’s choice to support authorization in various data platforms from small-scale to enterprise-grade production environments. At Ahana, engineers are working on the Presto-Ranger integration, aiming to support global fine-grained data access control across all catalogs for Presto, while also providing auditing and monitoring of user access. We would like to collaborate with the Privacera and share our learnings, what we developed so far, and also hope to shed light on the future work of the Ranger Presto Plugin with Apache Ranger committer.
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.
