> Key: FLINK-14296
> URL: https://issues.apache.org/jira/browse/FLINK-14296
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Reporter: Dawid Wysakowicz
> Priority: Major
> Labels: pull-request-available
>
> I want to suggest using Optional for optional parameters in classes such as SqlCreateTable/SqlCreateView/SqlTableColumn etc.
> Right now we must check against null at different locations e.g.:
> {code}
> SqlNodeList partitionKey = sqlCreateTable.getPartitionKeyList();
> if (partitionKey != null) {
> partitionKeys = partitionKey
> .getList()
> .stream()
> .map(p -> ((SqlIdentifier) p).getSimple())
> .collect(Collectors.toList());
> }
> {code}
