Runtime events

Runtime events are typed events emitted by Core during computations (refresh, sorting, filtering, model transitions).

1) When to use

• observe which updates the grid performs,
• collect diagnostics and metrics,
• integrate custom effects in the UI adapter.

2) Wiring

import { createDataGridApi } from "@affino/datagrid-core"

const api = createDataGridApi({ rowModel, columnModel })
await api.start()

const unsubscribe = api.onRuntimeEvent(event => {
  if (event.kind === "rows-refresh") {
    // diagnostics
  }
})

// later
unsubscribe()

3) Recommendations

• Do not block the handler; keep it fast.
• Keep diagnostics/logging in a separate layer.
