Hello, I need to implement LookupTableSource in my code, so I created a class {code:java} public LookupRuntimeProvider getLookupRuntimeProvider(LookupContext context) { CCDynamicLookUpFunction = new CCDynamicLookUpFunction(); returnTableFunctionProvider.of(tableFunction); } {code} {code:java} public class CCDynamicLookUpFunction extends TableFunction<RowData> {} {code} In the class CCDynamicLookUpFunction, I have fetched my data and executed the collect func {code:java} public void eval(Object... keys) { RowData row = dataReader.getNext(); System.out.println(row.toString()); collect(row); }{code} I'm sure the row is not null. But I find that the data I've collected doesn't seem to have any effect {code:java} +I(17978,2020-03-23T00:00:00.189760,F,A,true,0,-32768,-2147483648,-9223372036854775808,-18446744073709551616,-3.1,-3.14,-3.141291000) +I(17978,2020-03-23T00:00:00.189760,F,A,true,0,-32768,-2147483648,-9223372036854775808,-18446744073709551616,-3.1,-3.14,-3.141291000) | +I | -2147483648 | e0f22c444f807abbd6a38ac0fc2... | 2021-12-14T11:09:46.772 | (NULL) | (NULL) | (NULL) | (NULL) | (NULL) | (NULL) | (NULL) | (NULL) | (NULL) | (NULL) | (NULL) | (NULL) | (NULL) | {code} Can you tell me why? -- This message was sent by Atlassian Jira (v8.20.1#820001)
