Plans that are likely to become invalid and are not cached are those plans that reference data that is partitioned across segment/query execution nodes of the data store, plans that are complex, and plans that reference objects that are not “built-in” (primitive) objects. The effect is that most plans which are generated on a query dispatch (master) node are not cached, whereas most plans generated on an execution (segment) node are cached."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Query plan management in shared distributed data stores","description":"The invention identifies and caches query plans in a shared-nothing distributed data store that are unlikely to become invalid because they do not reference objects that are likely to be changed or de","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9646051","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
