Hi all, I try to create table through Table&SQL Api to read protobuf local file. The job is successfully finished, but the table has no data loaded, pretty wired. Anyone could help me?

tableEnv.executeSql("CREATE TABLE metric (\n" +
                "  metric_name STRING,\n" +
                "  function_name STRING,\n" +
                "  line_number INT\n" +
                ") WITH (\n" +
                " 'connector' = 'filesystem',\n" +
                " 'path' = '" + parameter.get("input_file") + "', \n" +
                " 'format' = 'protobuf',\n" +
                " 'protobuf.message-class-name' = 'MetricTest',\n" +
                " 'protobuf.ignore-parse-errors' = 'true'\n" +
                ")");
Table t = tableEnv.from("metric");
t.execute().print();

Here is result:

~/Downloads/flink-1.17.0/bin/flink run target/import-metric-event-1.0-SNAPSHOT.jar --input_file metric_test
Job has been submitted with JobID 9128383c4d60cccaa252145478f31ee5
Empty set

And here is the protobuf file:

metric_name: "test_metric_name"
function_name: "test_function_name"
line_number: 111

Protobuf file:

syntax = "proto3";

package metric;

message MetricTest {
  string metric_name = 1;
  string function_name = 2;
  uint32 line_number = 3;
}

Protobuf support for file system currently isn't supported
