<pre>
mariadb区别于mysql会在binlog的第一个事件Rotate_Event里也会采用checksum逻辑,而mysql是在第二个binlog事件之后才感知是否需要处理checksum
导致maraidb只要是开启checksum就会出现binlog文件名解析乱码

It does not override any existing entries in the deprecation map.
This is to be used only by the developers in order to add deprecation of
keys, and attempts to call this method after loading resources once,
would lead to <tt>UnsupportedOperationException</tt>
If you have multiple deprecation entries to add, it is more efficient to
use #addDeprecations(DeprecationDelta[] deltas) instead.
