public class JdbcBulkLoadBatchRequest
extends JdbcRequest

A JDBC request that sends a batch of a file to the server. Used when handling SqlBulkLoadCommand command.

Field Summary

Fields

Modifier and Type	Field	Description
static int	CMD_CONTINUE	Next batch comes in this request and there are more batches.
static int	CMD_FINISHED_EOF	This is the final batch of the file and everything went well on the client side.
static int	CMD_FINISHED_ERROR	This is the final batch from the client and there was an error on the client side, so terminate with error on the server side as well.
static int	CMD_UNKNOWN	A sentinel to indicate that cmd field was not initialized.
