Hi! MARK CALLAGHAN пишет:
Are checksums used for log pages? I did not see anything in ma_loghandler.c for this.
Look for TRANSLOG_PAGE_CRC and you will find.
Can I do a hot copy/backup of a table? That is can I copy the data and index files while transactions may be in progress for them and then replay log files to recover them?
Now for moving tables you have to stop mysqld and for backup use mysqldump. We plan hot backup driver in future versions.
I prefer a FLUSH LOGS command that is limited to Maria not all things that might be considered a log in MySQL. Are there plans to provide more engine specific commands?
There is no other interface at the moment. and plugin can't add its own commands. [skipped row chwcksum question as it is not loghandler related]
