|
| For example, this This may be used in conjunction with User Option Options Binder to return all the users into a dropdown selection. If the users' user records are large (in the ten tens of thousands), it is recommended to set the "Pause sync after idle" to a larger value and the sync will continue to update the cache in the background. If the dropdown selections are unlikely to change in a very short interval, it is recommended to set the "Sync Cache Interval" to a larger value too so that the server does not perform a new cache again in a short span of time. |
