Storage

Sync Engine provides two database access points on Context: an async IndexedDB database and a synchronous in-memory database. Both are backed by Uni-KV.

Databases

// Async IndexedDB database
ctx.indexedDB: DatabaseAsync<General, General>;

// Synchronous in-memory database
ctx.memoryDB: DatabaseSync<General, General>;

Existing stores include localContext20000, remoteContext10000, remoteContext20000 (all storing Stat values). These are used internally by the Context wrapper for stat caching.

Uni-KV API

SDK re-exports generic Uni-KV types:

type StoreAsync<T>;        // asynchronous store
type StoreSync<T>;         // synchronous store
type DatabaseAsync<D, M>;  // async database of stores and metadata
type DatabaseSync<D, M>;   // sync database of stores and metadata
type StoreOperations<T>    // Store.batch() payload type

Stores expose get, set, delete, clear, keys, values, entries, and batch. Databases expose getStore, getStoreNames, deleteStore, clearStores, getMeta, setMeta, and dispose.

RecordStore

type RecordStore = StoreAsync<RecordStat>;

Persists synchronization record entries. getRecordStore() selects the current local/remote filesystem namespace.

const records = ctx.getRecordStore();

await records.set('note.md', {
  isDir: false,
  local: 'local-uid',
  remote: 'remote-uid',
});

const record = await records.get('note.md');

Context Record Store Methods

Method	Purpose
getRecordStore	Gets current or named RecordStore.
deleteRecordStore	Deletes current or named record store.
clearRecordStores	Clears every record store.
recordStoreExists	Tests whether current or named record store exists.
