Hi @hzyuemeng1, in your terms we translate this as "sql -> table api -> 
runtime". But actually it is more like "sql api with calcite -> runtime". 
In the long-term view we will further optimize the "sql api with calcite" 
part.

@twalthr ,do we implement this base on table api such as sql -> table api 
-> runtime, or new plan:sql -> calcite->whole stage codegen -runtime.

I think we should leave this generic. It might also contain things like 
YARN application id or whatever there might come in the future.

Do you mean this globally? Also replacing `deployment` by `gateway` in the 
configuration file?

I also thought about the naming. In general, we call components that submit 
Flink jobs "client". So the entire effort will be called "SQL Client". The SQL 
Client consists of a CLI Client and SQL Gateway. SQL server might confuse user 
with Microsofts products.

Is this the point at which batch queries will fail? 
Can we fail earlier with a better error message?

> 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}

I don't think we should document features that are not there yet (or at

I would move the `Iterator` out of the `TableSink` for better separation of 
concerns. A `TableSink` should only be responsible to emit the data, not for 
receiving it.

According to the JavaDocs `TableSink.configure()` must return a configured 
copy of the `TableSink` and not the `TableSink` object itself.

Rename to `ResultType` to avoid confusion with `java.lang.reflect.Type`?

More details about the purpose of this class would be good. What kind of 
properties are stored? What is the scope of the configuration?

[FLINK-8607] [table] Add a basic embedded SQL CLI client

## What is the purpose of the change

This PR implements the first part of the implementation plan described in 
FLIP-24.

```
Goal: Add the basic features to play around with Flink's streaming SQL.

- 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)
```

Additionally, this PR also supports retraction queries and the SET 
operation for setting properties.

The client can be started using `./bin/sql-client.sh embedded`.

A table source must be defined in `./conf/sql-client-defaults.yaml` (for 
example a CSV table source, an example can be found in the test resources 
directory).

The client supports two modes for viewing results. A `changelog` mode or 
`table` mode. They can be selected by setting the `execution.result-mode` 
property.

The code is still work in progress. There are a couple of things that can 
be improved:

- Add more logging instead of swallowing exceptions
- Use Flink's ConfigOptions where applicable (e.g. for better default value 
handling and validation)
- Maybe make the record result retrieval blocking?
- Tests for the LocalExecutor
- Some basic tests for other classes (maybe for CLI classes as well?)
- More deployment options (support for YARN, FLIP-6?)
- Documentation


## Brief change log

- New module `flink-sql-client`
- New executable script in `flink/bin`
- Minor visibility changes in other modules

## Verifying this change

Manually verified. Further tests will follow.

## Does this pull request potentially affect one of the following parts:

  - Dependencies (does it add or upgrade a dependency): yes
  - The public API, i.e., is any changed class annotated with 
`@Public(Evolving)`: no
  - The serializers: no
  - The runtime per-record code paths (performance sensitive): no
  - Anything that affects deployment or recovery: JobManager (and its 
components), Checkpointing, Yarn/Mesos, ZooKeeper: no
  - The S3 file system connector: no

## Documentation

  - Does this pull request introduce a new feature? yes
  - If yes, how is the feature documented? not documented
