you the progress of inplace alter table and row log buffer usage
- (x 100%, it's 4-digit. 10000 means 100.00%)
- Innodb_onlineddl_rowlog_rows
Shows how many rows are stored in row log buffer.
- Innodb_onlineddl_rowlog_pct_used
Shows row log buffer usage in percent ( *100%, it's 4-digit. 10000 means 100.00% ).
- Innodb_onlineddl_pct_progress
Shows the progress of inplace alter table. It might
be not so accurate because inplace alter is highly
depend on disk and buffer pool status.
But still it is useful and better than nothing.
- Add some log for inplace alter table
XtraDB/InnoDB will print some message before and
after doing some task.
