net.wicp.tams.common.binlog.parser.event.ExecuteLoadQueryLogEvent

public final class ExecuteLoadQueryLogEvent
extends QueryLogEvent

Event responsible for LOAD DATA execution, it similar to Query_log_event but before executing the query it substitutes original filename in LOAD DATA query with name of temporary file.

• 4 bytes. The ID of the file to load.
• 4 bytes. The start position within the statement for filename substitution.
• 4 bytes. The end position within the statement for filename substitution.
• 1 byte. How to handle duplicates: LOAD_DUP_ERROR = 0, LOAD_DUP_IGNORE = 1, LOAD_DUP_REPLACE = 2
