-**The Table API: an experimental feature**
+Flink's Table API is a a SQL-like expression language embedded in Java and
Scala.
+Instead of manipulating a `DataSet` or `DataStream`, you can create and
work with the `Table` relational abstraction.
+Tables have a schema and allow running relational operations on them,
including selection, aggregation, and joins.
+A `Table` can be created from a `DataSet` or a `DataStream` and then
queried either using the Table API Operators or using SQL queries.

> Project: Flink
> Issue Type: New Feature
> Components: Table API
> Affects Versions: 1.1.0
> Reporter: Vasia Kalavri
> Assignee: Vasia Kalavri
>
> This issue covers the task of supporting SQL queries embedded in DataSet
> programs. In this mode, the input and output of a SQL query is a Table. For
> this issue, we need to make the following additions to the Table API:
> - add a {{tEnv.sql(query: String): Table}} method for converting a query
> result into a Table
> - integrate Calcite's SQL parser into the batch Table API translation process.
