DESCRIPTION: One of great things about mysqlbinlog was that its output was human-readable SQL, so it was possible to edit it manually or with help of scripts. With RBR events and BINLOG 'DpiGShMBAAAALQAAADcBAA...' statements this is no longer the case. This WL task is about making BINLOG statements to be human-readable (either as an option or by default The approach of this WL is to some extent an alternative to WL#38, WL#40, WL#41. HIGH-LEVEL SPECIFICATION: Suggestion 1 ------------ Original syntax suggestion by Kristian: BINLOG WITH TIMESTAMP xxx SERVER_ID 1 MASTER_POS 415 FLAGS 0x0 TABLE db1.table1 AS 1 COLUMNS (INT NOT NULL, BLOB, VARCHAR(100)) FLAGS 0x0 TABLE db2.table2 AS 2 COLUMNS (CHAR(10)) FLAGS 0x0 WRITE_ROW INTO db1.table1(1,3) VALUES (42, 'foobar'), (10, NULL) FLAGS 0x2 UPDATE_ROW INTO db2.table2 (1) (1) VALUES FROM ('beforeval') TO ('toval'), FROM ('a') TO ('b') FLAGS 0x0 DELETE_ROW INTO db2.table2 (1) VALUES ('row_to_delete') FLAGS 0x0; This is basically a dump of what is stored in the events, and would be an alternative to BINLOG 'gwWEShMBAA...'.
