Extract All: This will read and remove the records from the form store. If this mode runs twice, the second time will be empty unless new records are submitted. This mode is suitable for batch processing, for example running it once an hour and pushing all records into JDBC. If there are multiple Form DataSources reading simultaneously, there will be no duplicate records. Avoid using the extract modes with multiple flows which will cause the source to be read multiple times.

Extract One: This will read and remove at most one record from the form store. This mode will be used when a job is fired for each submission, when you need immediate propagation of the record into the next stage of a process. Be careful to use this mode with multiple flows in Composite DataSource, because each request from the source will return another record, which is not the same.

Scan All: This is the default and non-destructive mode, which leaves the data records in the form store. Use this mode if you need to inspect the submitted records without processing them.
