> Generate 画nique CorrelationId for Each Correlate Node
> -----------------------------------------------------
>
> Key: CALCITE-7045
> URL: https://issues.apache.org/jira/browse/CALCITE-7045
> Project: Calcite
> Issue Type: Improvement
> Reporter: suibianwanwan
> Priority: Major
>
> As discussed in
> [https://lists.apache.org/thread/l5ls7hxmrkp6vqqmffxs4cq4dnv95x36] :
> Currently in SubQueryRemove, new Correlates are created based on the
> CorrelationId from the original RelNode. When this subQuery requires multiple
> Correlate expansions or when multiple subQueries share the same CorrelationId
> and are expanded separately, multiple Correlates with identical CorrelationId
> may be generated.
> This can cause difficulties during Decorrelate processing and lead to errors
> in some scenarios.
