A
Data
is
generated
by
most
every
interaction
we
have
in
every
location,
whether
at
home,
at
work,
in-store
shopping
online
and
at
your
local
restaurant,
every
person
will
contribute
to
an
endless
amount
of
data
generated
by
their
computer
tablet,
phone
watch,
embedded,
sensors
credit
card
and
technology
we
have
yet
to
invent.
Until
recently,
we
didn't
appreciate
the
power
of
this
seemingly
random
and
unrelated
data
information
was
stored
in
many
places,
not
connected
and
rarely
reviewed.
A
Today
we
are
beginning
to
build
the
necessary
skills
and
solutions
to
gather
mine
and
connect.
Big
Data
success
in
a
big
data
economy
requires
business,
no
matter
the
industry
or
size
to
harness
a
commodities
such
as
big
data,
and
create
timely
and
actionable
insights
to
quickly
respond
to
customers,
lesson
risk
while
taking
risk
and
boost
market
share
and
profits.
At
datastax,
we
have
focused
on
enabling
big
data
applications
and
transforming
business
since
the
very
beginning
of
the
big
data
movement
for
datastax
customers,
big
data
no
longer
consists
of
unconnected
and
random
bits
of
information.
A
It
is
the
platform
that
powers,
the
next
generation
of
applications
used
to
leverage,
connections,
relationships
and
preferences,
providing
the
ability
to
change
a
customer's
experience
in
real
time.
The
companies
that
put
brilliant
minds
to
work,
the
ones
that
know
the
most
about
their
customers
and
can
make
each
customer
feel
like
their
company
is
built
just
for
them.
These
are
the
businesses
poised
for
success
at
datastax.
This
is
what
we
think
about
all
the
time
we
build
the
big
data
platform,
so
you
don't
have
to.
B
B
B
C
D
B
D
B
D
B
C
B
B
C
Okay,
come
on
hey,
we
talked
about
in
memory
set
with
Cassandra
persons.
This
me
a
shared
shelters
with
got
it
with
Cassandra
purses.
Someone
might
ask
why
wait
for
the
solution,
our
work
from
the
problems
and
we
had
a
broadened.
We
had
to
content,
we
had
200
million
of
documents,
nearly
20
traffic
data,
and
we
need
to
do
full
test
searches
in
this.
C
C
We
we
try
to
do
this
in
this
using
a
material
process,
but
our
service
rst
suffering
and
we
we
knew
our
all
problem
and
then
we
need
to
resolve
it.
We
did
start
with
our
requirements,
we
need,
we
needed
a
database.
Well,
we
we
we
save
or
information.
Obviously
we
choose
Cassandra.
Why
is
necessary
to
explain
here
the
other?
The
other
choice
was
a
little
harder.
We
need
I
understood
in
a
marker.
C
Ok,
let's
try,
but
before
two
before
we
work,
we
ask
yourself:
has
somebody
hot
right
cut?
The
Sun
problem?
Has
somebody
tried
it
is
before
us
cool
we
using
something
we
found
several
proposed.
This
is
was
true,
so
somebody
has
hung
somebody
tied
it.
Some
of
them
made
it,
but
there
was
there
were
something
we
didn't
like:
we,
we
knew
their
products,
we
need
the
way,
the
other
guys
a
hot
right.
We
need
some
of
the
mistakes
and
we
made
the
decision
to
do
to
do
it
yourself.
C
We
integrate
the
same
with
Cassandra
and
to
be
faster.
We
save-
or
in
this
in
others,
in
an
instant
memory
using
finished
by
the
net
account
in
the
system.
Francine,
you
seem
process
the
data
and
start
the
English.
This
indecisive
in
this
isn't
this
in
this
is
same
in
finished
part
and
the
raw
data
is
stored
in
Cassandra.
In
this
way
mark
we
can
check.
We
improve
the
certainty
that
the
sensational
Lucien
appear
weak.
You
can
see.
C
We
are
this
time
faster,
that
the
traditional
see
also
we
have
all
information
distributed
with
Cassandra
and
all
in
this
a
replicated
using
a
thin
spot,
and
we
also
a
week-
and
we
also
have
a
strong
excuse
me.
Half
a
strong
assistant,
esta
fall
to
relax
are
the
salty
solutions.
Is
that
your
status
earth
is
work
status,
shares
in
Akron,
stone
or
platform
estate
Oprah
in
duration
platform
developed.
C
D
G
E
Hello,
everyone
I'm
going
to
show
you
how
to
be
more
effective
in
Cassandra
development,
with
Achilles,
so
to
introduce
myself
my
name
is
you
Hydra
I'm,
freelance
developer,
currently
working
on
liban
project
for
the
orange
group,
I'm,
a
Cassandra,
passionate
and
creator
of
Achilles?
So
why
a
Cadiz?
It
is
not
yet
another
pan
sauce,
persistent
manager.
E
We
want
you
to
focus
more
on
data,
modeling,
modern
functional
requirements
and
less
on
technique
on
plumbing
it
should
be
delegated
to
the
framework
and
last
but
not
least
well
at
least
has
a
complete
documentation,
plus
a
twitter
limo
as
an
advanced
tutorial.
So
for
entity
mapping.
We
support
all
kind
of
almost
everything
compound
primary
Keys
composite
partition
keys.
You
can
have
time
you
ID
any
support,
consistency,
level,
define
a
statically
and
so
on.
Just
have
a
look
at
the
dock.
E
The
persistent
manager
is
that
less
so
you
can
use
a
single
internal,
and
so
it's
straight
safe.
You
have
common
mr.
to
access
data,
lots
of
configuration
parameters
and
we
are
tight
spring
integration,
so
you
have
factory
beam
to
create
the
persistent
manager,
but
if
you
hate
xml
config,
you
have
also
some
sample
java
convict
asses
I
need
slight
quiet
dsl.
So
to
do
a
slight
way.
You
provide
partition.
Key
from
clustering
to
class
ring
set
the
ordering
the
bounding,
and
then
you
have
the
results.
E
If
you
want
to
craft
manually
your
sequel
statement,
you
can
do
type
query.
In
that
case,
Achilles
we
play
as
a
data
mapper
a
plane
data
mapper
for
you.
If
you
want
to
use
native
sequel
function,
you
can
rely
on
the
native
Korean
support.
So
it's
quite
straightforward
for
special
Cassandra
feature.
Support,
actually
support
all
the
distributed.
Contrast
natively
through
an
API
you
can,
with
the
option
window,
provide
consistency,
level
TJ
an
atom
stop
at
one
time.
Okay,
now,
as
a
Java
developer,
I
spend
lost
of
my
time.
Writing
Jeremy,
test.
D
E
Come
on
come
on,
come
on,
I
saw
its
back
and
this
work
out
of
the
box,
but
that's
not
all.
If
you
want
to
dig
into
detail,
you
can
activate
debug
logging,
so
you
can
have
DDL
statement
and
prepare
statement
with
man
values.
So
you
can
understand
what
is
done
under
the
hood
by
Achilles
roadblock
for
future.
We
are
planning
to
support
secondary
index
as
small
support,
beam
validation
because
it's
useful,
some
DL
template
allows
spin
data
and
of
course
we
will
support
all
new
customer
to
that
0
feature
which
are
coming
very
soon.
E
B
G
So
today,
we'd
like
to
discuss
analytics
approach
and
scalability
approach
of
solution
them
several
issues,
so
I
visualized
that
statistics.
We
have
many
statistics,
token
statistics,
time,
zero
statistics,
average
median
values
and
float
analysis
based
on
max
value,
which
we
have
already
calculated
so
watch
what
we
have
implemented
top
and
statistics
we
use.
Will
we
read
data
from
database
as
the
result
of
my
face
is
number
of
entities
and.
G
B
D
F
F
B
B
D
D
B
F
Hello,
everybody,
it's
a
pleasure
to
be
today
with
you.
My
name
is
bubbles.
A
jet
ski
and
I
also
would
like
to
share
our
experience
in
a
brief
with
Cassandra
project
so
who
we
are
cognito,
ms,
a
polish
company
delivering
several
business
applications
for
customers,
both
in
Poland
and
also
brought.
We
are
windows,
azure
cloud
partners,
since
we
are
delivering
a
lot
of
Windows
Azure
applications
and
n
dot
net
for
for
the
customers.
In
the
same
time,
we
also
work
in
for
datastax.
F
F
It
combines
several
semantic
web
standards
like
0
WL
and
a
description
logic
profile
sparql
for
acquiring
rdf
in
in
a
bottom
of
the
project
and
natural
language
interface.
The
challenge
here
is
to
manage
the
huge
repositories
that
can
be
accessed
by
a
high
traffic,
a
lot
of
users
and
can
be
propelled
with
the
big
inputs.
F
What
what
we
get
as
a
benefit
by
using
cassandra
is
much
easier
and
faster
searching
capabilities
out
of
out
of
this
solution,
much
easier
and
faster
data
modeling.
We
have
the
high-performance
whole
reliability
for
the
for
the
whole
system
and,
last
but
not
least,
lower
data
maintenance
costs
so
basically
for
the
five
minutes.
I
believe
this
is
this.
Is
it
thank
you
very
much.
B
B
B
You
didn't
get
a
blue
screen
of
death,
oh
good,
all
right,
all
right,
great
okay!
You
got
you
want
your
phone.
Ok,
that's
fine!
Me!
Don't
unplug!
It
too
fast
am
I
crashed
computer!
Okay.
Did
anyone
else,
leave
anything
up
here,
all
right,
good?
Okay,
so
that
was
it
for
lightning
talks
and
I
have
to
congratulate
everybody.
There
was
real
lightning
that
was
two
and
a
half
minutes.
Okay,
all
right!
Thank
you
very
much
for
all
our
lightning
talk.
Speakers.
B
So
this
is
it
we're
done
for
the
day.
I
want
to
thank
everybody
that
showed
up.
I
mean
we
had
a
few
hiccups
here
in
there
of
it
man.
It
was
a
lot
of
good
I
got
to
talk
to
a
lot
of
people
today
and
I.
Think
that's
one
of
the
best
things
about
this
conference.
You
know,
especially
when
you
have
it
small,
like
this
I,
don't
know
if
you've
ever
been
to
something
like
Java
one
or
even
oracle.
B
Openworld,
please
don't
say
if
you
did,
but
you
know
when
you
have
it
over
six
city
blocks,
you
don't
get
a
meet
people
and
I
like
that
kind
of
conference.
Where
you
get
to
talk
to
people
in
the
hallway,
hey.
What
are
you
doing
or
people
come
up
to
me
and
say:
hey
I
saw
a
video.
You
did
and
you're
stupid
all
right.
Let's
talk
about
that.
You
know
and
only
happened
like
twice
today.
B
I,
don't
feel
bad
right
so,
but
this
is
what
we
hope
that
we
get
our
community
is
the
strongest
part
of
Cassandra.
If
you
look
at
what
we
have
as
a
team,
we're
all
working
together.
If
you
look
at
IRC
the
mailing
list,
what
we
do
in
these
conferences,
meetup
groups,
there's
just
an
insane
amount
of
people
that
are
talking
to
each
other
and
that's
the
best
part
of
open
source.
It's
not
one
company
trying
to
drive
the
message.
B
Datastax
irrelevant
in
this
case
I
hate
to
say
that
John,
don't
panic,
but
community
is
where
it's
at
datastax.
Doesn't
own
Cassandra,
you
do
you
can
go
on
the
jira
and
write
a
ticket
for
a
feature
you
want.
You
can
submit
a
patch
for
something
you
want,
because
you
can
get
all
the
source
code.
You
can
get
every
bit
of
details
about
what
happened
with
the
source
code.
It's
all
in
there.
Even
the
get
comments,
so
some
other
kind
of
funny.
Actually,
but
it's
all
yours
and
you
could
do
that.
B
B
Okay,
so
tomorrow
I
just
little
housekeeping
tomorrow,
we're
gonna
be
doing
more
workshops,
and
so,
if
you're,
if
you're
involved
in
that
we're
gonna
be
starting,
the
same
time
was
88
clock
in
the
morning
is
when
we
start
that
it's
really
hitting
Kevin
eight
o'clock,
it's
a
little
early
I
know
it's
like
not
nerd
time.
You
realize
that
right.
Ten
is
good
hi,
maybe
yeah.
No,
it's
eight
o'clock.
B
B
So
it's
it
to
stay
so
we're
going
to
do
our
rebel,
a
lead,
and
so
this
program
we
used
to
call
it
MVP,
which
would
change
name
as
Christian
said,
but
this
is
really
about
recognition
and
its
peer
to
peer.
That's
bad
joke,
but
it's
a
peer
recognition.
It's
nothing
that
you
know
a
secret
committee
comes
up
with.
It's
not
me
dreaming
up
these
names.
B
These
are
voted
on
by
people
in
the
community
and
what
we're
looking
for
people
who
go
beyond
just
normal,
just
normal
everyday
user
interaction
where
they're
pushing
the
envelope
so
to
speak
in
community,
and
that's
what
really
makes
this
community
great
and
not
only
that
this
year
we
a
lot
of
people
are
expected
to
summit
in
San
Francisco.
We
didn't
do
it
there,
we're
doing
it
here.
B
So
yeah
30
we
have
30
rebel
elite,
so
the
rebel
leap
thing
is
all
about.
If
you
guys
follow
me
on
Twitter,
and
if
you
don't,
you
should
but
I
talk
a
lot
about
the
rebel
forces,
and
that
was
one
of
the
things
we
brought
at
the
last
summit
in
San.
Francisco
is
this
rebels,
and
let
me
explain
that
a
little
bit
the
reason
I
say
that
all
the
time
is
because
a
lot
of
people
that
start
with
Cassandra
usually
are
doing
it
against
the
grain.
B
If
you're
in
a
shop,
that's
using
Oracle
or
sequel
server
or
post
gross,
or
my
sequel,
you're,
probably
everyone's
pretty
happy
with
that,
and
when
you
bring
in
Cassandra-
and
you
say
you
know
what
I
want
to
do
things
differently-
you're,
probably
getting
a
little
bit
of
ridicule
and
if
not
you're,
going
to
work
in
a
great
place,
but
I
know
I
got
it
like.
Why
would
you
bring
that
in
here?
No
Oracle
works
great.
We
love
paying
money
to
Larry
Ellison.
Why
would
you
do
this
to
us
and
then
what
happens?
B
Is
you
figure
out
that
it
really
did
work?
You
know,
and
then
everybody
says
well:
okay,
maybe
that
did
work
and
before
you
know
it,
you
have
production
systems
running
Cassandra
and
you
are
that
rebel
alley
that
we're
looking
for
the
rebels,
that
you
made
a
decision
and
you're
fighting
that
fight
and
we
want
to
help
you
so
the
rebel
elite.
Are
these
people
out
there
helping
and
the
people
you
see
up
here.
These
are
people
that
were
all
voted
on
by
the
community
and
we
have
nine
people
here.
B
B
Make
me
with
these
are
a
rebel
late
that
we
have
here.
We
have
a
gift
for
you,
of
course,
because
you
are
the
elite
and
Brady.
Do
you
have
that
runs
your
hands
up?
So
what
we
did
this
here
is.
This
is
really
nerdy
but
cool.
I
wish
I
was
at
elite
now.
These
are.
These
are
raspberry
pi,
developer
kits
like
full,
bore
and
the
reason
we're
going
with
a
raspberry,
pi
Andy
cobley.
Where
are
you
raising
had
he
was
teaching
an
entire
college
course
on
Cassandra
running
a
raspberry
pi.
B
B
Alright,
one
more
thing
before
we
go
because
we
don't
want
everyone
to
leave
empty-handed
right.
This
is
like
Oprah
right,
you
get
a
car,
you
get
a
car,
a
joke,
isn't
as
big
here
right:
okay!
So
when
you're
walking
out
what
we
have
for,
you
is
a
little
gift
for
you
to
take
home
and
that's
Cassandra
right,
so
I'll
come
on
up.
Al
has
been
working
tirelessly
on
what
we're
trying
to
do
is
give
you
an
experience
of
Cassandra
that
is
really
portable
and
complete.
So
what
Al
has
done?
D
It's
USB
drive
for
gig
use,
USB
Drive,
it's
got
a
Linux
VM
on
it,
vm
DK
you
should
be
able
to.
If
you
have
vmware
player,
just
double
click
it
and
it's
just
start
copy
over
and
start
right
up
and
kisan.
It
boots
up
and
starts
cassandra
and
you
can
connect
to
it
from
dev
center
or
whatever
client
you
like
to
use
it'll
actually
print
on
the
screen
in
the
vm.
D
The
connection
details
that
you
need
and
that's
it
if
you
have
a
mac
and
you're
using
VirtualBox,
there's
a
little
extra
work
to
do,
but
I
will
post
more
on
the
blog
pretty
soon
on
how
to
do
that.
If
you
get
stuck,
we
just
figure
that
out
today
but
enjoy
dev
center
is
on
there
as
well.
There
should
be
mac,
OS,
64-bit
windows,
32-bit
and
windows
64-bit
in
the
dev
center
directory.
When
you
get
started
plugging
in
there's
a
start
here,
HTML
file,
double
click
that
and
that
will
get.
D
D
B
So
what
I
would
ask
you
guys
are
the
beta
testers.
You
are
the
first
wave
on
this
community.
We
want
feedback,
because
what
we're
going
to
try
to
do
with
this
is
give
this.
When
we
go
to
meet
ups,
when
we're
talking
to
people
about
hey,
you
want
to
try
Cassandra
here,
it
is,
go
and
use
it.
We
want
your
feedback.
We
want
to
create
a
really
easy
to
use
experience
for
newcomers
to
Cassandra.
B
So
if
you
have
something
you
want
to
talk,
you
know
like
hey,
you
got
some
ideas
about
it
or
you
did
you
have
some
feedback
it
to
work.
It's
going
to
Yeah
right.
If
you
have
any
feedback,
just
let
us
know
you
know
this
is
a
true
community.
We
want
feedback
and
we
want
to
hear
good
feedback
good
or
bad,
and
let
us
know
all
right:
where
should
they?
Let
us
know?
Where?
Should
they
let
us
know?
Oh
god
am
I
gonna
give
him
by
where.
B
I
was
gonna,
give
you
my
email
address,
but
then
I
shuddered,
you
probably
all
know
my
email
address
anyway
anyway.
So
last
announcement,
because
we
like
giving
away
stuff,
we
have.
We
have
four
vendors
down
into
in
the
expo
area
that
are
doing
a
raffle
during
the
reception,
so
you
still
have
a
chance
to
get
more
stuff.
So,
let's
go
down.
Let's
do
that.
Thank
you
very
much.
It's
A
Wrap
see
you
next
year.
