Class DatabaseProvider

Database-backed flag provider that polls an injected IFlagStore.

Loads initial state via store.loadFlags() on start(), then polls at a configurable interval. On poll failure, keeps the last good snapshot, logs via the injected logger, and exposes unhealthy status().

Example

const provider = new DatabaseProvider(
  { store: myFlagStore, refreshIntervalMs: 60000 },
  ctx.runtime,
  ctx.logger,
);
await provider.start();
