+# write permissions

+- 2 phase commit
+- whole row to write callback
+- write callback can reject in which case we.. 
+  Well no data changed but we need to get the data back to the client.
+  We could
+    1. record the db version that failed and somehow get that back to the client
+    2. bump the db version of the record, causing all clients to re-pull it
