@@ -32,12 +32,11 @@ Main Differences Between the Two Planners
1. Blink treats batch jobs as a special case of streaming. As such, the
conversion between Table and DataSet is also not supported, and batch jobs will
not be translated into `DateSet` programs but translated into `DataStream`
programs, the same as the streaming jobs.
2. The Blink planner does not support `BatchTableSource`, use bounded
`StreamTableSource` instead of it.
-3. The Blink planner only support the brand new `Catalog` and does not support
`ExternalCatalog` which is deprecated.
-4. The implementations of `FilterableTableSource` for the old planner and the
Blink planner are incompatible. The old planner will push down
`PlannerExpression`s into `FilterableTableSource`, while the Blink planner will
push down `Expression`s.
-5. String based key-value config options (Please see the documentation about
[Configuration]({{ site.baseurl }}/dev/table/config.html) for details) are only
used for the Blink planner.
-6. The implementation(`CalciteConfig`) of `PlannerConfig` in two planners is
different.
-7. The Blink planner will optimize multiple-sinks into one DAG (supported only
on `TableEnvironment`, not on `StreamTableEnvironment`). The old planner will
always optimize each sink into a new DAG, where all DAGs are independent of
each other.
-8. The old planner does not support catalog statistics now, while the Blink
planner does.

yes, nice catch.
