+Although Flinkâs Table & SQL API allows to declare queries in the SQL
language. A SQL query needs to be embedded within a table program that is
written either in Java or Scala. The table program needs to be packaged with a
build tool before it can be submitted to a cluster. This limits the usage of
Flink to mostly Java/Scala programmers.
+
+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 code. The
*SQL Client CLI* allows for retrieving and visualizing real-time results from
the running distributed application on the command line.
