You may never need to subscribe to your item in RAW mode.
In fact, if some clients need that no updates are filtered, they could subscribe to the item in MERGE mode with the "unfiltered" flag set,
that is, by issuing table.setRequestedMaxFrequency("unfiltered") on your table.
This differs from RAW mode in two ways:
  • The snapshot is included in the update flow; this holds regardless that the subscription is the first one (and the snapshot comes from the Data Adapter) or it is not the first one (and the snapshot is generated by Lightstreamer).
  • If any field is missing in an update coming from the Data Adapter, it is considered as an unchanged field (whereas in RAW mode it is forwarded as a null). This is the same behavior as MERGE mode.
