-----------------------------------
Summary: Refactoring the Filter operator of Arrow ArrowAdapter
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
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
