----------------------------------------------
There is no PR and it seems that nobody is actively working on this so removing
the fix version.

> Key: CALCITE-6636
> URL: https://issues.apache.org/jira/browse/CALCITE-6636
> Project: Calcite
> Issue Type: Improvement
> Components: arrow-adapter
> Affects Versions: 1.38.0
> Reporter: Caican Cai
> Assignee: Caican Cai
> Priority: Major
> Fix For: 1.39.0
>
>
> Recently, I tried to complete
> https://issues.apache.org/jira/browse/CALCITE-6293
> I found a problem. When building the Filter operator structure, we did not
> effectively fill the List<TreeNode> conditionNodes according to operators
> such as and and or, so our current Filter operator structure can only support
> the and operator
> Currently, I have a way to support simple or operators, but I cannot support
> complex nested and+or and other operator joint queries, such as
> {code:java}
> String sql = "select \"intField\", \"stringField\"\n"
> + "from arrowdata\n"
> + "where (\"intField\" > 1 and \"stringField\" = '2') or \"intField\" = 0";
> {code}
> I plan to add operator information to List<TreeNode> conditionNodes so that
> we can finally assemble a suitable Filter structure
