the Operation object describing the current state of the long-running operation
Throws
IOException

Schema
getSchema()
Gets the Schema defined within the connected data source.
Each data source may have at most one schema defined within it. This method extracts the
schema definition to use with the current connector's data repository.

ListenableFuture<Operation>
unreserve(String queue)
Unreserves previously polled Item entries in a specific queue.
When a connector issues a poll(PollItemsRequest) of the indexing queue, the
returned Item entries are marked internally as reserved so that they are
unavailable for a future poll(PollItemsRequest) request. This prevents two possibly
different threads from processing the same Item. This method allows the connector to
reset the queue to make all of its entries available again.
Parameters
queue
the queue to unreserve, (null for default queue)
Returns
ListenableFuture that the caller uses to obtain the result of an unreserve
operation (using get())
