@wuchong @libenchao I have introduced a new connector param `write-null-string-literal` ``` When serializing to protobuf data, this is the optional config to specify the string literal in protobuf's array/map in case of null values. By default empty string is used. Only string value in protobuf's complicated type can be specified. Numeric type will always pick 0 as default value. ``` ## Extra improvements 1. I use `SimpleCompiler` of janino to compile all my code which is the same way in `org.apache.flink.table.runtime.generated.CompileUtils` 1. Add IT cases of source and sink in SQL. 1. Add `write-null-string-literal`. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
