/** |

|
|
* This class does a full resync of the database by |
|
5
|
|
|
* enqueuing an outbound action for every single object |
|
6
|
|
|
* that we care about. |
|
7
|
|
|
* |
|
8
|
|
|
* This class, and its related class Jetpack_Sync_Module, contain a few non-obvious optimisations that should be explained: |
|
9
|
|
|
* - we fire an action called jetpack_full_sync_start so that WPCOM can erase the contents of the cached database |
|
10
|
|
|
* - for each object type, we page through the object IDs and enqueue them by firing some monitored actions |
|
11
|
|
|
* - we load the full objects for those IDs in chunks of Jetpack_Sync_Module::ARRAY_CHUNK_SIZE (to reduce the number of MySQL calls) |
|
12
|
|
|
* - we fire a trigger for the entire array which the Jetpack_Sync_Listener then serializes and queues. |
