/**
Signal that the first part of handler commit is finished, and that the
committed transaction is now visible and has fixed commit ordering with
respect to other transactions. The commit need _not_ be durable yet, and
typically will not be when this call makes sense.
This call is optional, if the storage engine does not call it the upper
layer will after the handler commit() method is done. However, the storage
engine may choose to call it itself to increase the possibility for group
commit.
In-order parallel replication uses this to apply different transaction in
parallel, but delay the commits of later transactions until earlier
transactions have committed first, thus achieving increased performance on
multi-core systems while still preserving full transaction consistency.
The storage engine can call this from within the commit() method, typically
after the commit record has been written to the transaction log, but before
the log has been fsync()'ed. This will allow the next replicated transaction
to proceed to commit before the first one has done fsync() or similar. Thus,
it becomes possible for multiple sequential replicated transactions to share
a single fsync() inside the engine in group commit.
Note that this method should _not_ be called from within the commit_ordered()
method, or any other place in the storage engine. When commit_ordered() is
used (typically when binlog is enabled), the transaction coordinator takes
care of this and makes group commit in the storage engine possible without
any other action needed on the part of the storage engine. This function
thd_wakeup_subsequent_commits() is only needed when no transaction
coordinator is used, meaning a single storage engine and no binary log.

Type of BINLOG_CHECKSUM_ALG. Include checksum for log
events in the binary log. Possible values are NONE and
CRC32; default is NONE.
--binlog-commit-wait-count=#
If non-zero, binlog write will wait at most
binlog_commit_wait_usec microseconds for at least this
many commits to queue up for group commit to the binlog.
This can reduce I/O on the binlog and provide increased
opportunity for parallel apply on the slave, but too high
a value will decrease commit throughput.
--binlog-commit-wait-usec=#
Maximum time, in microseconds, to wait for more commits
to queue up for binlog group commit. Only takes effect if
the value of binlog_commit_wait_count is non-zero.
--binlog-direct-non-transactional-updates
Causes updates to non-transactional engines using
