Sorry; The above flag was wrong in 3.23.7; This is fixed in 3.23.8.
Rick> DELAY_KEY_WRITE has the same issue (should be on by default, but show

I am not completely sure if it was fixed in 3.23.7; Anyway, in my
running 3.23.8 version I have:
| concurrent_insert | ON |
| delay_key_write | ON |
Rick> Also, the DELAY_KEY_WRITE description in 10.2.3 starts off: "If enabled (is

Rick> Which is correct?
Both. The problem is that the above is the description of the
'delay_key_write' flag, which is not exactly the same as the
'delay_key_write' startup option for mysqld. I shall at once rename
the mysqld startup option to 'delay_key_write_for_all_tables'.
I have now updated the manual about this.
