From YouTube: Two Years with Vitess: How JD.com Runs the World's Largest Vitess - Xuhaihua & Jin Ke Xie , JD.com
Description
Join us for Kubernetes Forums Seoul, Sydney, Bengaluru and Delhi - learn more at kubecon.io
Don't miss KubeCon + CloudNativeCon 2020 events in Amsterdam March 30 - April 2, Shanghai July 28-30 and Boston November 17-20! Learn more at kubecon.io. The conference features presentations from developers and end users of Kubernetes, Prometheus, Envoy, and all of the other CNCF-hosted projects
JD.com serves 99% of China's consumers, we have always had to innovate on infrastructure in order to meet the demands of scale and speed. In 2017, we adopted Vitess to help us scale MySQL. Two years on, JD.com now operates the world' largest Vitess on Kubernetes deployments. In this presentation, I will introduce how we use Vitess in JD.com. I will also share my personal understanding of Vitess in the Chinese context. Finally, I present a demo to show how we fully exploit the value of Vitess. My presentation will demonstrate: 1. The value that Vitess brings to JD.com: how we use Vitess to reduce costs on machines and development 2. Frequently encountered problems: as one of the world's largest Vitess users, we want to share the problems we have encountered with Vitess and how to solve them 3. Practical examples in my demo: how to quickly built our projects with reusable Vitess modules

Of
these
will
be
recorded
into
technology.
Also,
we
have
another
tool
corporation.
There
will
be
two
CTL
and
also
we
see
Tod
it
providing
the
external
functions.
For
example,
I
have
urgent
nowmail,
some
have
some
shots
already,
I
want
to
add
some
extra
shots
now,
if
I
want
to
change
for
the
other
nodes,
for
example,
want
to
download
or
upload
the
notes,
then
into
so
I
can
use
the
Vitas
video
to
operate
it
so.

Id
is
1
and
5
and
then
years
like
whitening
Lisa
and
they
know
hi
insert
and
I
can
easily
and
the
neighbors
listen
the
to
name
both
Lisa,
but
it
has
been
put
into
shots
when
I'm
do
the
inquiry
based
on
the
ID
works.
For
example,
it's
going
to
say
that
ID
is
5.
Then
it's
going
to
beauty
to
shot
0
because
I
use
I
need
for
shopping,
and
then
it's
going
to
go
to
me.

Feedback
queries
we
feedback
to
the
eventually
to
the
apps
and
way
ticket
through
the
watch.
My
mechanism
were
using
EB
etcd
to
enable
original
data
storage.
Vicky
data
have
a
watch
mechanism
which
were
real-time
watch
route,
information
and
other
changes
in
original
data,
so
that
the
data
can
be
synchronized
with
our
shots
to
enable
a
more
efficient
synchronizing
and
many
JD.
Businesses
have
internal.
B
B

C

C
One
is
J
transfer,
what
does
it
mean,
so
many
of
our
previous
services
will
use
my
sequel
directly
and
now,
if
the
basis
is
online,
so
we
are,
you
know,
switching
into
weight
has
to
transfer
some
of
our
services.
So
we
real-time
extract
and
synchronize
a
BTK
being
like
that.
This
is
only
limited
to
this
stage.
B
C
B
C
To
restart
the
services
used
to
connect
with
my
safe
call
cluster
now
switching
to
by
betas.
This
is
what
we
don't
for
transfer.
It's
mainly
used
to
folders
key
accounts
of
big
businesses
in
China,
where
there
used
to
be
many
nodes
on
any
data.
So
in
this
way
we
don't
have
to
consider
the
storages
files
in
the
past.
Maybe
there
are
32
charts
and
we
have
to
expand
the
key
space
by
ourselves.
It's
very
difficult
and
time-consuming
now
we're
using
a
BTS
key
space
with
no
problems
or
storage
at
all.
C
C
The
data
from
all
nodes-
my
Zuko,
knows
their
master
replicas,
datas
latency
and
after
the
retrieving,
this
data
will
be
moved
to
the
internal
storage
and
after
right,
written
name.
It
will
conduct
analysis
just
to
tell
whether
there's
a
problems
between
the
master
replicas
latency.
If
there's
some
problem
with
the
master
replicas
system,
then
we'll
select
our
the
system
with
the
least
with
the
least
latency
to
switch
it
and
also,
if
this
part,
if
this
master
replica
is
dead,
then
it
will
trigger
a
trigger
of
switching
to
another
master.
B
B
C
For
business,
launching
there
are
two
steps.
The
first
step
is
the
request.
So
to
request
the
data
warehouse
resources
will
be
allocated,
for
example,
how
much
shipping
you
know
how
much
internal
memory,
so
that's
normally
what
we
do.
So
after
the
request,
the
project
manager
will
approve
on
the
request
and
after
the
approval
based
on
jeebies
resources,
there
will
be
a
DBA
approval
and,
after.
B
C
Approval
based
on
their
own
professional
knowledge,
to
evaluate
whether
the
tables
creation
has
some
risk
factors,
whether
it's
combined
with
regulations
and
after
that
the
online
table
will
be
created,
not
a
decoration.
There
will
be
some
more
interfaces
in
maybe
a
TBS
to
apply
for
resources,
scheduling.
B
B
C
Just
a
database
creation,
but
the
to
change
the
structure
of
the
table
is
not
that
easy
for
our
R&D
people.
They
have
some
knowledge
of
photography
database
after
their
understanding
is
somewhat
different
from
ours.
We
know
that
for
some
you
know
business
requests,
there
are
no
primary
keys.
This
is
this
is
what
we
are
not
recommending,
or
maybe
the
primary
key
is
not
Auto
coded.
C
We
would
recommend
the
auto
link
function
or
maybe
there's
some
deep
pre,
deprecated
storage,
engine
or
deprecated
characters,
or
maybe
he
has
created
the
table
and
created
another
one,
but
the
table
actually
already
exists
and
there's
some
data
in
the
table
as
well,
so
now
using
a
dumper
sequence
to
delete
it.
But
this
is
a
risky
behavior
and
there
are
some
even
lower
mistake,
like
a
syntax.
B
B
B
C
B
C
B
C
Need
to
change
that
the
Mojo's,
even
if
our
there's
some
syntax
errors
in
some
modules,
but
because
of
the
low
coupling
level
picked
up
I
can
introduce
the
attacker
modo
module
to
create
a
table.
If
there's
some
syntax
error,
then
they
can
tell
the
business
departments
that
there's
a
syntax
error
in
the
sequel.
So
there's
no
need,
for
you,
know
p.m.
and
TBA
approval
to
identify
the
error
and
eventually
resubmitting
the
request
and
some
of
the
tables
key
primary
keys
and
other
restraints.
B
C
C
Can
execute
it
online
a
short
ago
sequence
and
now
look
like
whether
there's
a
table
online?
If,
yes,
the
now
Hotel
Rd,
that
your
table
already
exists,
no
need
to
submit
again
or
submit
that
the
sinkhole
again,
oh,
that's
even
the
table
does
not
exist,
then
fill
in
is
holiness
rows.
I
can
examine
eight
and
verify
these
are
a
master
replicas
information
or
whether
these
sinkholes
are
compliant.

Share
the
second
person
and
second
part
and
the
third
an
old
man,
because
of
the
time
restraint
I
was
quickly
caught
certainty,
so
I
talked
about
what
are
some
of
the
problems
and
oceans.
Janey
has
in
content
and
on
top
set
and
next
I
will
share
our
future
plans.
I'll
start
with
challenges:
JD
is
operating
fair
to
say
the
largest.
Oh,
the
largest
in
China
fate
has
cluster.
