Hello Andrés
did you notice that both transactions are trying to update records with
same *accountid='3235296' *
and that they lock the same index page? *space id 5806 page no 69100 n bits

Yup, but a far I understand...
I made a
select balance for update where accountid=3235296 lock in shared mode;
over the same accountid , so the second transacion just would need to wait
to the first transaccion to finish...
That is why I'm confuse if I have a Deadlock o a wait lock
Andrés,
may be you can enable the general log, recreate the deadlock,
and attach the general log?
If I had to reason as InnoDB, what I see is two updates statements that
arrive and want to update the same record,
I would be confused exactly as InnoDB is because I would not know which

Hi,
I'd really appreciate help with reading this db deadlock notice.
Essentially, I'd like to understand:
-what holds the lock that TX2 is waiting on index `token` of table
`eviltwin/user_sessions`? I thought it'd be TX1 (hence deadlock ?), yet
it appears that TX1 holds no locks
to delete the row. This of course requires the removal of its
presence in the indxexes, including `token`, but because of the earlier
exclusive lock set by TX1 this cannot be accomplished without waiting for
the lock to be freed. TX2 waits.
Hence, the deadlock.
I'm wondering if granting X-locks

INTO t VALUES (100), he will receive a deadlock.
The algorithm is that a cursor in InnoDB always travels in one direction.
User 2 has his cursor waiting on the row (110) for an exclusive row next-key lock.
