-**Table API and SQL are experimental features**
+Apache Flink features two relational APIs - the Table API and SQL - for
unified stream and batch processing. The Table API is a language-integrated
query API for Scala and Java that allows to compose queries from relational
operators such as selection, filter, and join in a very intuitive way. Flink's
SQL support is based on [Apache Calcite](https://calcite.apache.org) which
implements the SQL standard. Queries specified in either interface have the
same semantics and specify the same result regardless whether the input is a
batch input (DataSet) or a stream input (DataStream).
