Jelte Fennema is a senior software engineer at Microsoft, where he works on the Citus database engine for PostgreSQL which in turn is used by Azure CosmosDB. In his talk, Jelte shared his work on the cancellation problem: the inability to predictively cancel queries sent to a horizontally scalable PostgreSQL setup. This problem occurs when cancellation database queries do not land on the same node that is executing the original query.
