Table API and SQL queries have the same semantics regardless whether their
input is bounded batch input or unbounded stream input. In many cases,
continuous queries on streaming input are capable of computing accurate results
that are identical to offline computed results. However, this is not possible
in general case because continuous queries have to restrict the size of the
state they are maintaining in order to avoid to run out of storage and to be
able to process unbounded streaming [...]
-Flink's Table API and SQL interface provide parameters to tune the accuracy
and resource consumption of continuous queries. The parameters are specified
via a `QueryConfig` object. The `QueryConfig` can be obtained from the
`TableEnvironment` and is passed back when a `Table` is translated, i.e., when
it is [transformed into a DataStream]({{ site.baseurl
}}/dev/table/common.html#convert-a-table-into-a-datastream-or-dataset) or
[emitted via a TableSink](../common.html#emit-a-table).
