########## src/main/tla/ConsistentFailover/markdown/HAGroupStore.md: ########## @@ -0,0 +1,445 @@ +# HAGroupStore -- Peer-Reactive Transitions and Auto-Completion + +**Source:** [`HAGroupStore.tla`](../HAGroupStore.tla) + +## Overview + +`HAGroupStore` models the peer-reactive transitions and auto-completion actions of the Phoenix Consistent Failover protocol. These actions correspond to the `FailoverManagementListener` (`HAGroupStoreManager.java` L633-706), which reacts to peer ZK state changes via `PathChildrenCache` watchers, and the local auto-completion resolvers from `createLocalStateTransitions()` (L140-150). Review Comment: Yes. The spec's runtime state machine operates on the per-cluster ZK znode managed by HAGroupStoreClient, which is the source of truth for HA group state. Catalog reads and writes happen out of band of the failover protocol and are intentionally not modeled. -- This is an automated message from the Apache Git Service.
