-------------------------------
Description:
As we deprecates {{execute}} method and {{explain}} method because of buffering
SQLs/Tables execution problem. This issue aims to introduce a new method named
createDmlBatch to support executing and explaining the batching queries.
{code:java}
interface TableEnvironment {
/**
* Create a DmlBatch instance which can add dml statements or Tables to the
batch,
* the planner can optimize all added statements and Tables together for
better performance.
*/
DmlBatch createDmlBatch();
}
interface DmlBatch {
/**
* add insert statement to the batch.
*/
void addInsert(String insert);
/**
* add Table with the given sink table name to the batch.
*/
void addInsert(String targetPath, Table table);
/**
* execute all statements and Tables as a batch.
*
* The added statements and Tables will be cleared when this method.
*/
ResultTable execute() throws Exception;
/**
* returns the AST and the execution plan to compute the result of the all
statements and Tables.
*
* @param extended if the plan should contain additional properties. e.g.
estimated cost, traits
*/
String explain(boolean extended);

The method looks like:
