> Common CachedLookupFunction for All connector
> ---------------------------------------------
>
> Key: FLINK-13252
> URL: https://issues.apache.org/jira/browse/FLINK-13252
> Project: Flink
> Issue Type: New Feature
> Components: Connectors / Common, Table SQL / API
> Reporter: Chance Li

> shortly, it's a decorator pattern:
> # A CachedLookupFunction extends TableFunction<Row>
> # when needing the cache feature, the only thing is to construct this
> CachedLookupFunction with the real LookupFunction's instance. so it's can be
> used by any connector.
> # CachedLookupFunction will send the result directly if data has been cached
> or, to invoke the real LookupFunction to get data and send it after this data
> has been cached.
> # will have more cache strategies such as All.
> should add a new module called flink-connector-common.
> we also can provide a common Async LookupFunction using this pattern instead
> of too much implementation.
