This document provides information about performance improvements and new features in MySQL 5.7. It includes benchmarks showing MySQL 5.7 outperforming previous versions in tasks like point selects, InnoDB throughput, and connections per second. New capabilities in 5.7 like InnoDB improvements, replication, MySQL Fabric, and security enhancements are highlighted. The refactoring of MySQL 5.7's parser and optimizer to be more modular and extensible is also summarized.

“The

simply
*huge*,

many

Perhaps
I'm

I

Refactoring
• Challenge:
– Overly

hard
to

• SoluOon:
– Create

– Create
an
AST
(Abstract
Syntax
Tree)
from
the
parse
tree
and
the
user's
context.
– Have
syntax
rules
that
are
more
precisely
defined
and
are
closer
to
the
SQL
standard.
– More
precise
error

– Beder
support

Locks

• User-­‐level

–
When
accessing
some

–
When
table

are
not
appropriate
• Request
mulOple
locks
by
issuing
a
series
of
GET_LOCK
statements
• Replaces
custom

implementaOon
– With
one
based
on
the
MDL
lock
manager
– Deadlocks
between
different
connecOons
acquiring
user-­‐level
locks,

locks,
and
those
waiOng
for

are
properly
detected
