-------------------------------
Summary: When deserialize UDF array type from json string, throw
an exception
Key: CALCITE-4062
URL: https://issues.apache.org/jira/browse/CALCITE-4062
Project: Calcite
Issue Type: Wish
Reporter: xzh_dz
Function serialization and deserialization are often involved. When I run some
tests, I find that some functions have exceptions during deserialization.
The exception can be reproduced as below:
RelWriterTest:
{code:java}
@Test void test() {
final FrameworkConfig config = RelBuilderTest.config().build();
final RelBuilder builder = RelBuilder.create(config);
final RelNode rel = builder
.scan("EMP")
.project(
builder.call(new MockSqlOperatorTable.SplitFunction(),
builder.field("ENAME"), builder.literal(",")))
.build();
String relJson = RelOptUtil.dumpPlan("", rel,
SqlExplainFormat.JSON, SqlExplainLevel.EXPPLAN_ATTRIBUTES);
String s = deserializeAndDumpToTextFormat(getSchema(rel), relJson);
System.out.println(s);
}
MockSqlOperatorTable:
public static class SplitFunction extends SqlFunction {
public SplitFunction() {
super("split", new SqlIdentifier("split", SqlParserPos.ZERO),
SqlKind.OTHER_FUNCTION, null,
null, OperandTypes.family(SqlTypeFamily.STRING,
SqlTypeFamily.STRING), null,
SqlFunctionCategory.USER_DEFINED_FUNCTION);
}
@Override public RelDataType inferReturnType(SqlOperatorBinding opBinding) {
final RelDataTypeFactory typeFactory =
opBinding.getTypeFactory();
return
typeFactory.createArrayType(typeFactory.createSqlType(SqlTypeName.VARCHAR), -1);
}
}
{code}
Exception：
{code:java}
