+
+```ts
+const notifyManager: object;
+```
+
+Defined in: [packages/query-core/src/notifyManager.ts:144](https://github.com/TanStack/query/blob/main/packages/query-core/src/notifyManager.ts#L144)
+
+Handles scheduling and batching callbacks in TanStack Query.
+
+## Type Declaration
+
+### batch()
+
+```ts
+readonly batch: <T>(callback) => T;
+```
+
+Batches all updates scheduled inside the passed callback.
+This is mainly used internally to optimize query client updating.
+Batches can be nested; the queue is only flushed once the outermost `batch` call finishes.
+The return value of `callback` is passed through.
+
+#### Type Parameters
+
+##### T
+
+`T`
+
+#### Parameters
+
+##### callback
+
+() => `T`
+
+#### Returns
+
+`T`
+
+### batchCalls()
+
+```ts
+readonly batchCalls: <T>(callback) => BatchCallsCallback<T>;
+```
+
+All calls to the wrapped function will be batched.
+
+#### Type Parameters
+
+##### T
+
+`T` *extends* `unknown`[]
+
+#### Parameters
+
+##### callback
+
+`BatchCallsCallback`\<`T`\>
+
+#### Returns
+
+`BatchCallsCallback`\<`T`\>
+
+### schedule()
+
+```ts
+schedule: (callback) => void;
+```
+
+Schedules a function to be run on the next batch.
+By default, the batch is run with a `setTimeout`, but this can be configured via `setScheduler`.
+
+#### Parameters
+
+##### callback
+
+`NotifyCallback`
+
+#### Returns
+
+`void`
+
+### setBatchNotifyFunction()
+
+```ts
+readonly setBatchNotifyFunction: (fn) => void;
+```
+
+Use this method to set a custom function to batch notifications together into a single tick.
+Framework adapters use this to plug in their own batching primitive, so that a single query
+update only triggers one re-render instead of one per subscriber.
+
+#### Parameters
+
+##### fn
+
+`BatchNotifyFunction`
+
+#### Returns
+
+`void`
+
+#### Example
+
+```ts
+import { notifyManager } from '@tanstack/query-core'
+import { batch } from 'solid-js'
+
+notifyManager.setBatchNotifyFunction(batch)
+```
+
+### setNotifyFunction()
+
+```ts
+readonly setNotifyFunction: (fn) => void;
+```
+
+Use this method to set a custom notify function.
+This can be used to for example wrap notifications with `React.act` while running tests.
+
+#### Parameters
+
+##### fn
+
+`NotifyFunction`
+
+#### Returns
+
+`void`
+
+### setScheduler()
+
+```ts
+readonly setScheduler: (fn) => void;
+```
+
+Configures a custom callback that schedules when the next batch runs.
+The default behavior is `setTimeout(callback, 0)`.
+
+#### Parameters
+
+##### fn
+
+`ScheduleFunction`
+
+#### Returns
+
+`void`
+
+#### Example
+
+```ts
+import { notifyManager } from '@tanstack/query-core'
+
+// Schedule batches in the next microtask
+notifyManager.setScheduler(queueMicrotask)
+
+// Schedule batches before the next frame is rendered
+notifyManager.setScheduler(requestAnimationFrame)
+
+// Schedule batches some time in the future
+notifyManager.setScheduler((cb) => setTimeout(cb, 10))
+```
