Abstract
Methods and systems for locality-aware query planning in a distributed computing system are provided. A query is received from a client device at a gateway node geographically located in a first database region. A plurality of query plans for execution of the query are generated at the gateway node. A first query plan of the query plans is configured to cause communication between the gateway node and a subset of computing nodes that are geographically located in a first external database region that is external to the first database region. A respective cost for each of the query plans is determined. The respective cost for the first query plan is based on an indication of a latency between the first database region and the first external database region. An optimal query plan from the query plans is determined and executed based on each respective cost for the query plans.
