PersistentCacheIndexManager

public final class PersistentCacheIndexManager

---

Persistent cache indexes can improve performance of local query execution. The PersistentCacheIndexManager controls index creation and lifecycle.

This is not the same as Cloud Firestore Indexes. Persistent cache indexes are optional indexes that only exist within the SDK to assist in local query execution.

To get an instance, call getPersistentCacheIndexManager.
