Author: Sun Jincheng (Jinzhu) In Apache Flink version 1.9, we introduced pyflink module to support Python table API. Python users can complete data conversion and data analysis. However, you may find that pyflink 1.9 does not support the definition of Python UDFs, which may be inconvenient for Python users who want to extend the system’s […] Java Code Examples for org.apache.flink.table.api.java.StreamTableEnvironment The following examples show how to use org.apache.flink.table.api.java.StreamTableEnvironment . These examples are extracted from open source projects. AS SELECT syntax. As mentioned above flink does not own the data. Therefore this statement should not be supported in Flink. In Flink’s statement, such a query can be expressed with CREATE TEMPORARY VIEW.

Before Flink 1.10 you can configure the statebackend, checkpointing and restart strategy via the StreamExecutionEnvironment. And now you can configure them by setting key-value options in TableConfig , see Fault Tolerance , State Backends and Checkpointing for more details.
