Yes, I’m sure.
env.setRuntimeMode(RuntimeExecutionMode.STREAMING);
This is my current complete write code.
```
public static DataStream<RowData>
readHudiDataStream(StreamExecutionEnvironment env, ParameterTool params,
Map<String, String> schema) throws Exception {
String tableName = params.get("read_tablename");
String basePath = params.get("read_basepath");
String primaryKey = params.get("read_primarykey");
String hoodieTableType = params.get("read_hoodie_table_type");
String precombing = params.get("read_precombing");
String name = HoodieTableType.COPY_ON_WRITE.name();
if (hoodieTableType.equals("cow")) {
name = HoodieTableType.COPY_ON_WRITE.name();
}
if (hoodieTableType.equals("mor")) {
name = HoodieTableType.MERGE_ON_READ.name();
}
Map<String, String> options = new HashMap<>();
options.put(FlinkOptions.PATH.key(), basePath+tableName);
options.put(FlinkOptions.TABLE_TYPE.key(), name);
options.put(FlinkOptions.READ_AS_STREAMING.key(), "true");
options.put(FlinkOptions.PRECOMBINE_FIELD.key(),precombing);
options.put(FlinkOptions.READ_START_COMMIT.key(), "earliest");
options.put("read.tasks","5");
HoodiePipeline.Builder builder = HoodiePipeline.builder(tableName);
for (Map.Entry<String, String> entry : schema.entrySet()) {
builder.column(entry.getKey() + " " + entry.getValue());
}
builder.pk(primaryKey)
.options(options);
// Get DataStream of RowData
DataStream<RowData> rowDataDS = builder.source(env);
return rowDataDS;
}
```
