-----------------------------------
Labels: pull-request-available (was: )
> PreparedSplitterNumericParameters.withBatchSize reads past maxVal
> -----------------------------------------------------------------
>
> Key: FLINK-40748
> URL: https://issues.apache.org/jira/browse/FLINK-40748
> Project: Flink
> Issue Type: Bug
> Components: Connectors / JDBC
> Affects Versions: jdbc-4.1.0
> Reporter: Martijn Visser
> Assignee: Martijn Visser
> Priority: Major
> Labels: pull-request-available
> Fix For: jdbc-5.0.0, jdbc-4.1.1
>
>
> `getParameterValues` uses the split formula
> `JdbcNumericBetweenParametersProvider` had before FLINK-38046; when the batch
> size does not divide the range, `bigBatchNum` goes negative and the last
> split ends above `maxVal`, so the source reads rows above the configured
> upper bound (`[5, 9]` in batches of 4 gives `[5,7],[8,10]`). `withBatchNum`
> is not affected (exhaustive check up to 200 values).
> Fix: the last split ends at `maxVal`, and `minVal > maxVal` is rejected as
> the provider does.
