> Replace TableConfig with Configuration
> --------------------------------------
>
> Key: FLINK-16835
> URL: https://issues.apache.org/jira/browse/FLINK-16835
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Reporter: Timo Walther
> Priority: Minor
> Labels: auto-deprioritized-major
>
> In order to allow reading and writing of configuration from a file or
> string-based properties. We should consider removing {{TableConfig}} and
> fully rely on a Configuration-based object with {{ConfigOptions}}.
> This effort was partially already started which is why
> {{TableConfig.getConfiguration}} exists.
> However, we should clarify if we would like to have control and traceability
> over layered configurations such as {{flink-conf,yaml <
> StreamExecutionEnvironment < TableEnvironment < Query}}. Maybe the
> {{Configuration}} class is not the right abstraction for this.
> [~jark], [~twalthr], and [~fhueske] discussed the configuration options (see
> comments below) and concluded with the following design:
> {code:java}
> public static final ConfigOption<Duration> IDLE_STATE_RETENTION =
> key("table.exec.state.ttl")
> .durationType()
> .defaultValue(Duration.ofMillis(0));
> public static final ConfigOption<Integer> MAX_LENGTH_GENERATED_CODE =
> key("table.generated-code.max-length")
> .intType()
> .defaultValue(64000);
> public static final ConfigOption<String> LOCAL_TIME_ZONE =
> key("table.local-time-zone")
> .stringType()
> .defaultValue(ZoneId.systemDefault().toString());
> {code}
> *Note*: The following {{TableConfig}} options are not preserved:
> * {{nullCheck}}: Flink will automatically enable null checks based on the
> table schema ({{NOT NULL}} property)
> * {{decimalContext}}: this configuration is only used by the legacy planner
> which will be removed in one of the next releases
> * {{maxIdleStateRetention}}: is automatically derived as 1.5*
> {{idleStateRetention}} until StateTtlConfig is fully supported (at which
> point only a single parameter is required).
