making a storage engine crash safe on a slave in MySQL 5.6

[Zardosht Kasheff]

Hello all,

I read that InnoDB is now crash safe on slaves in MySQL 5.6. I
understand that a way they do this is on committing a transaction on a
slave, they store the binary log position in an InnoDB table (which
makes that information transactionally maintained). I also understand
that this position is stored for each database, as databases may apply
the replication log in parallel.

Upon recovery of a slave, how does InnoDB report to MySQL where the
replication log should resume?

Can another storage engine similarly make itself crash safe on a
slave? Will there be any issues with multiple storage engines doing
so?

Thanks
