For example, when a node leaves or enters a multi-node system, the ownership of the entries in the ASDR table can change thus invalidating cached and replica entries. More specifically, the system and methods disclosed herein include searching an ASDR table for cached entries responsive to the system determining the multi-node system has changed. After finding a cached entry, the system may determine if the entry should be poisoned. The decision to poison the entry may be responsive to the creation time of the entry, the time when the change to the multi-node system occurred, and in the case of a replica, the owner of the replica's position in a replication chain relative to source of the replica."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for application-state, distributed replication table cache poisoning","description":"The present application is directed towards invalidating (also referred to as poisoning) ASDR table entries that are determined to be inaccurate because of changes to a multi-node system.
