> Add a basic embedded SQL CLI client
> -----------------------------------
>
> Key: FLINK-8607
> URL: https://issues.apache.org/jira/browse/FLINK-8607
> Project: Flink
> Issue Type: Sub-task
> Components: Table API & SQL
> Reporter: Timo Walther
> Assignee: Timo Walther
> Priority: Major
>
> This issue describes the Implementation Plan 1 of FLIP-24.
> Goal: Add the basic features to play around with Flink's streaming SQL.
> {code}
> - Add CLI component that reads the configuration files
> - "Pre-registered table sources"
> - "Job parameters"
> - Add executor for retrieving pre-flight information and corresponding CLI
> SQL parser
> - SHOW TABLES
> - DESCRIBE TABLE
> - EXPLAIN
> - Add streaming append query submission to executor
> - Submit jars and run SELECT query using the ClusterClient
> - Collect results on heap and serve them on the CLI side (Internal Mode with
> SELECT)
> - SOURCE (for executing a SQL statement stored in a local file)
> {code}
