Summary: SQL Calcite: Support custom Java types in UDF and UDTF
parameters and results
Key: IGNITE-29081
URL: https://issues.apache.org/jira/browse/IGNITE-29081
Project: Ignite
Issue Type: Bug
Reporter: Kirill Tkalenko
Assignee: Kirill Tkalenko
Support custom Java objects and {{BinaryObject}} in UDF and UDTF parameters and
results, including parameters declared as {{{}Object{}}}, {{{}Number{}}}, and
{{{}Serializable{}}}.
Currently, these types may cause SQL validation or generated code compilation
failures due to incorrect type inference and argument conversion. Custom
objects in UDTF result columns may also be incorrectly interpreted as SQL
records.
Ensure correct type mapping and argument conversion, and add integration tests
covering these cases.
