If you simply want to try out the SQL Client, you can also start a local cluster with one worker using the following command: For more information about setting up a Flink cluster see the Cluster & Deployment part. It requires only a running Flink cluster where table programs can be executed. The SQL Client is bundled in the regular Flink distribution and thus runnable out-of-the-box.
IMPACT CLIENT 1.11 HOW TO
This section describes how to setup and run your first Flink SQL program from the command-line. The SQL Client CLI allows for retrieving and visualizing real-time results from the running distributed application on the command line. The SQL Client aims to provide an easy way of writing, debugging, and submitting table programs to a Flink cluster without a single line of Java or Scala code. This more or less limits the usage of Flink to Java/Scala programmers. Moreover, these programs need to be packaged with a build tool before being submitted to a cluster. We recommend you use the latest stable version.įlink’s Table & SQL API makes it possible to work with queries written in the SQL language, but these queries need to be embedded within a table program that is written in either Java or Scala. This documentation is for an out-of-date version of Apache Flink.
