-------------------------------
Description:
as the
[FLIP-84|https://cwiki.apache.org/confluence/display/FLINK/FLIP-84%3A+Improve+%26+Refactor+API+of+TableEnvironment]
document described,
We propose to deprecate the following methods in TableEnvironment:
{code:java}
void sqlUpdate(String sql)
void insertInto(String targetPath, Table table)
void execute(String jobName)
String explain(boolean extended)
Table fromTableSource(TableSource<?> source)
{code}
meanwhile, we propose to introduce the following new methods in
TableEnvironment:
{code:java}
// synchronously execute the given single statement immediately, and return the
execution result.
ResultTable executeStatement(String statement)
public interface ResultTable {
TableSchema getResultSchema();
Iterable<Row> getResultRows();
}
// create a DmlBatch instance which can add dml statements or Tables to the
batch and explain or execute them as a batch.
DmlBatch createDmlBatch()
interface DmlBatch {
void addInsert(String insert);
void addInsert(String targetPath, Table table);
ResultTable execute() throws Exception ;
String explain(boolean extended);
}
{code}
We unify the Flink table program trigger behavior, and propose that: for
{{TableEnvironment}} and {{StreamTableEnvironment}}, you must use
{{TableEnvironment.execute()}} to trigger table program execution, once you
convert the table program to a {{DataStream}} program (through
{{toAppendStream}} or {{toRetractStream}} method), you must use
{{StreamExecutionEnvironment.execute}} to trigger the {{DataStream}} program.
