-------------------------------------
ok， thank you
> The MAP_CONTAINS_KEY function result does not necessarily correspond to the

> Key: CALCITE-6235
> URL: https://issues.apache.org/jira/browse/CALCITE-6235
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.36.0
> Reporter: Caican Cai
> Priority: Minor
>
> map_contains_key(map(1, 2), cast(1 as double) returns false but spark returns
> true.
> This may involve some node type conversion bug
> But I personally tend to think that this is a bug of Spark itself. Calcite
> does not necessarily need to return true.
