ERROR: Could not read entry at offset 946675767: Error in log format or read error.

一 问题描述

查看binlog里内容，发现无法正常查看：

mysqlbinlog --no-defaults -v master-bin.000543 > baidd_543.log

报错：

ERROR: Error in Log_event::read_log_event(): 'Event truncated', data_len: 1413827653, event_type: 109
ERROR: Could not read entry at offset 946675767: Error in log format or read error.

二 解决办法

添加-f参数，强制打开

mysqlbinlog --no-defaults -v -f master-bin.000543 > baidd_543.log

虽然有报错：

mysqlbinlog: /home/buildbot/buildbot/padding_for_CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX/mariadb-10.3.18/sql/log_event.cc:10883: Rows_log_event::Rows_log_event(const char*, uint, const Format_description_log_event*): Assertion `var_header_len >= 2' failed.
Aborted
但是能查看到baidd_543.log文件包含了完整内容
