This kind of deprecation does not work for Java. Please add the Java

> Replace Table.limit() by Table.fetch() and Table.offset()

> Key: FLINK-7821
> URL: https://issues.apache.org/jira/browse/FLINK-7821
> Project: Flink
> Issue Type: Improvement
> Components: Table API & SQL
> Affects Versions: 1.4.0
> Reporter: Fabian Hueske
> Assignee: Fabian Hueske
> Priority: Minor
>
> The Table API method limit() exists in two variants:
> - {{limit(offset)}} returns all but the first {{offset}} records.
> - {{limit(offset, fetch)}} returns {{fetch}} records starting from the
> {{offset}}'s record.
> Especially, the behavior of {{limit(offset)}} is confusing because one would
> rather expect a behavior of returning the {{offset}} first records instead of
> all but the {{offset}} first records.
> Moreover, the only way to return the first {{x}} records is to specify a
> {{0}} offset as {{limit(0, x)}}.
> I propose to deprecate and replace both {{limit()}} variants by two new
> methods {{Table.offset(offset)}} and {{Table.fetch(fetch)}} that can be
> combined as follows:
> {code}
> table.orderBy(...).fetch(x)
> table.orderBy(...).offset(x)
> table.orderBy(...).offset(x).fetch(y)
> {code}
