Infrastructure aware query optimization

A query optimizer comprising:

• one or more computer processors;
• and
• a memory storing instructions that, when executed by the one or more computer processors, cause the query optimizer to:
• receive a first query for a first set of requested data;
• determine a set of computing nodes in a network that can provide the first set of requested data;
• request, from an infra monitor, health scores for the set of computing nodes that can provide the first set of requested data, wherein the infra monitor receives infrastructure data from the network;
• select, based on the health scores, a subset of computing nodes from the set of computing nodes to service the first query;
• and
• request the first set of requested data from the subset of computing nodes.

A non-transitory computer-readable medium storing instructions that, when executed by a query optimizer, cause the query optimizer to:

• receive a first query for a first set of requested data;
• determine a set of computing nodes in a network that can provide the first set of requested data;
• request, from an infra monitor, health scores for the set of computing nodes that can provide the first set of requested data, wherein the infra monitor receives infrastructure data from the network;
• select, based on the health scores, a subset of computing nodes from the set of computing nodes to service the first query;
• and
• request the first set of requested data from the subset of computing nodes.
