A
B
Started
developing
a
new
experimental
SD
buck
and
dazing
on
them,
store
and
open
source
p.m.
library
which
is
specifically
designed
for
working
with
a
non-volatile
memories,
and
our
bucket
will
be
designed
for
non
spinning
disk,
like
SSD,
said,
VMI's,
etc,
and
the
main
idea
is
to
use
them
store
code
base
and
the
same
object,
handling
and
collections.
But
instead
of
writing
allocating
memory
for
the
objects
we
storing
it
in
the
to
the
memory
mapped
file.
B
This
memory
mod
file
is
divided
into
fixed
sized
blocks
to
cope
with
fragmentation.
You
know
you're
losing
some
sort,
we're
losing
part
of
the
storage
with
it
for
the
particular
small
files
and
for
this
this
beam
source
works
with
the
library
which
will
be
soon
open
source
which
uses
this
leap.
Pmm
library
and
it's
designed
to
handle
blocks
default
block
size
is
one
megabyte
for
data,
and
for
now
we've
got
eight
kilo
for
exit,
omap
related
entries
and
what.
B
Yeah,
each
each
object
have
vector
with
vector
with
block
IDs
and
how
to
read
and
write.
We
just
mapping
the
block
number
to
the
corresponding
pointer
in
virtual
memory,
which
is
parked
with
this
no
grammar
file
and
performing
just
simple
mem
copy
on
a
tool
to
write.
It
writes,
isn't
so
good
right
now,
Bob
us
for
read,
we
there's
page
cache
is
cable
utilized
and,
although
us
to
use
Colonel
page
cache
are
some
sort
of
lost
persons,
we
used
file
blog,
so
read
the
performance.
For
now.
It's
quite
quite
good.
B
B
The
scheme
is
that
when
the
block
is
updated
life
from
some
some
offset
to
the
Sun
lank
in
the
middle
of
the
block,
the
fall
contents
of
the
block
is
copied
and
later
our
the
changes
is
dirty
rangers
is
moved
basically
the
whole
back
end
for
for
this
objects
for
the
PM
store.
It's
some
sort
of
works
like
transactional.
B
A
soldier
like
we
write
for
each
transaction
stifle
writing
a
simple
transaction
lock,
which
includes
that
which
rocks
was
right,
written
which
was
deleting
which
blocks
are
updated
and
updated
blocks.
The
old
block
from
update
operations
are
released
only
after
the
transaction
commits
and
also
you
got
recovery
teams
for
the
startup
and,
what's
worth
noting
that
the
whole
index
of
the
objects
and
collections
are
kept
in
memory,
we
start
up
we're
just
rebuilding
from
each
block
metadata.
D
A
B
B
D
B
B
And
I
believe
I,
don't
know
when
I
could
tell
more
about
it.
It
killed
people
in
clarify
when
is
finally
open
source
at
it,
and
you
could
grab
the
code
and
test
it.
I
can
set
up
for
now
we're
testing
it
that
or
always
these
are
size
max,
sighs,
I,
remember
as
I
recall
correctly,
is
for
geeks
and
setups
for
us
these.
B
C
B
B
So
it
could
be
possible
to
just
make
a
new
buffer
row
class
which
take
these
blocks
marks
its
ass
reserved
that
it
couldn't
be
clear
that
it
couldn't
be
deleted
or
cleared
after
the
update
operation
and
pass
this
buffer,
and
there
will
be
read
by
the
end
point
of
the
when
their
message
will
be
constructed.
We
possible
to
just
a
copy
from
the
beautiful
memory
address
from
the
file.
Instead
of
taking
space
from
memory,
allocator
pool.
C
C
B
Yes
for
now,
unfortunately,
yes
and
the
to
avoid
losing
space
from
the
OSD
for
extended
matata
that
we
using
for
now
one
megabyte
blocks
we
working
to
improve
the
back
end
to
just
stop
small
rights
to
the
likes
for
to
the
half
of
the
block,
to
store
it
into
the
transaction
log
and
then
at
execute
when
they're
all
journal
is
resisted.
We
just
updated
in
place,
but
also
it
will
be
complicate
the
zero
read
path.
So
it
still
is
still
under
the
development.
B
B
The
whole
design,
if
I
started
with
trying
to
utilize
this
library
from
non-volatile
memory,
so
our
first
choice.
First
of
all,
you
tried
with
key
by
DB,
but
after
talking
sighs,
it
appeared
that
it's
not
heavily
developed
in
heavily
developer,
so
he
advised
us
to
use
jons
general
object,
store
interface,
leaf
or
use
it,
and
later
on
that
we
will,
we
will
trying
to
optimize
it
for
president
memory,
so
a
mem
store
was
obvious
choice
for
it.
B
D
Question
so
the
object
store
interface
currently
requires
some
kind
of
a
callback
based,
write
and
write
interface
right.
When
you
do
a
submit
transaction,
you
give
it
a
context
called
on
apply.
Put
on
complete
for
you.
I
would
imagine
if
that's
excessively
heavy
weight.
You
probably
have
a
finisher
bread,
whose
only
purpose
is
to
call
those
contexts.
B
D
D
Would
it
be
interesting
to
you
if
the
objects,
torque
lat
class,
supported
a
polling
base
to
asynchronous
right
lemon
aioli
so
that,
rather
than
you
needing
to
schedule,
a
call
back,
you
would
fill
in
a
ball
object
with
enough
state
that
the
object
store
client
can
check
to
see
whether
the
right
has
been
completed.
This
would
allow
us
to
serve
the
entire
right
from
single
op
thread,
pool
thread
without
needing
to
do
the
right
completion
component
from
a
different
thread.
D
It
might
buy
us
some
locality
in
the
case
of
extremely
low
latency
backends,
like
when
you're
building
sonor,
yet
they
thought
snot
not
flake
immediately,
but
I've
been
thinking
about
that
lately
and
changes
to
the
right
path.
I
assume
you're
perfectly
happy
with
having
a
synchronous,
read
right,
yeah.
D
I
was
thinking
that
each
op
threadpool
thread
could
have
a
vector
of
in
progress
operations
and
every
time
it
finishes
when
it
goes,
checks
with
via
other
ones
are
ready
to
make
more
progress
either
because
the
backend
is
completed
to
write
or
because
the
messages
come
in
and
that
might
a
lot
that
button
might
buy
a
similarity.
So
if
you
guys
have
any
thoughts
on
that,
that
would
be
an
interesting
conversation.
A.
D
Interesting
now,
with
that,
we
never
had
a
back
end
fast
enough
to
where
the
the
outdoor
interfaces
Ella
is
elegant.
In
some
sense,
it's
nice
and
contained
gives
you
transaction
ality,
but
it's
clunky
and
the
context.
Cheating
is
very
heavy,
though
probably
we
might
do
something
like
extend
the
address
order
phase
so
that
the
implementer
extent
implements
either
the
synchronous
version
or
da
synchronous
version
and
whichever
one
you
don't
implement
is
emulated,
which.
