Hi all,

So to summarise
- Auto create mysql.gtid_slave_pos_{innodb,tokudb,myrocks} if a
On Wed, Mar 8, 2017 at 4:58 PM, Kristian Nielsen transaction
is seen in one of those engines
- A --skip-gtid-auto-create-pos-table to disable this auto behaviour
- A stored procedure mysql.gtid_pos_add_engine() to facilitate manually adding an engine table.
What do you think, does this sound ok? Suggestions for better ways?
I like this idea very much!!!
I also like it very much. Let me add my 2 cents: I think skip-gtid-auto-create-pos-table should be enabled (skipping creation) by default in the 1st release of the new "per-engine mysql.gtid_slave_pos" feature. This respects the "principle of least surprise" when upgrading to a new version and could be changed in a next major version. To complete that, maybe adding some counters (statues) about: - number of transactions not spawning storage engine (could benefit the new feature), - number of cross storage engine transactions (needed XA, but exclusing mysql.gtid_slave_pos*) - number of transactions not spawning storage engine that updated a mysql.gtid_slave_pos in another SE (because skip-gtid-auto-create-pos-table=1) - maybe more...
