go-store

Group-namespaced SQLite key-value store with TTL expiry, namespace isolation, quota enforcement, and a reactive event system. Backed by a pure-Go SQLite driver (no CGO), uses WAL mode for concurrent reads, and enforces a single connection to ensure pragma consistency. Supports scoped stores for multi-tenant use, Watch/Unwatch subscriptions, and OnChange callbacks — the designed integration point for go-ws real-time streaming.

Quick Start

import "dappco.re/go/core/store"

st, err := store.New("/path/to/store.db")  // or store.New(":memory:")
defer st.Close()

st.Set("config", "theme", "dark")
st.SetWithTTL("session", "token", "abc123", 24*time.Hour)
val, err := st.Get("config", "theme")

// Watch for mutations
w := st.Watch("config", "*")
defer st.Unwatch(w)
for e := range w.Ch { fmt.Println(e.Type, e.Key) }

// Scoped store for tenant isolation
sc, _ := store.NewScoped(st, "tenant-42")
sc.Set("prefs", "locale", "en-GB")
