+## Using the Memory Temporary Store
+
+For some targets like Android 12/API 31, syncing of large datasets may cause disk IO errors due to the default temporary store option (file) used.
+To resolve this you can use the `memory` option, by adding the following configuration option to your application's `package.json`
+
+```json
+{
+  // your normal package.json
+  // ...
+  "op-sqlite": {
+    "sqliteFlags": "-DSQLITE_TEMP_STORE=2"
+  }
+}
+```
