Re: Time of Multiple Joins in AsterixDB

Thu, 22 Dec 2016 16:51:07 -0800

Exactly; I was just thinking of how to lazily set the parameters without counting disks or cores - i.e., of how to just ask the system to run everything with max-parallelism.

Yes, that would work.
However, if the cluster only has 128 available cores, it will use 128-way
(instead of 1000) parallelism for the computation.

So to use maxi-storage parallelism for scans but maxi-core parallelism
subsequently, one would just specify a large positive value >= the number
of available cores? (E.g., 10000)

Indeed, the change was merged yesterday.

If you grab the latest master, the computation parallelism can be set by
the parameter compiler.parallelism:
-- 0, the default, means to use the storage parallelism as computation
parallelism
-- negative value,  means to use all available cores in the cluster
-- positive value, means to that number of cores, but it will fall to
back
to use all available cores if the number is too large.

It would definitely also be fun to see how the newest more flexible

parallelism stuff handles this!  (Where you'd specify storage
parallelism
based on drives, and compute parallelism based on cores, both spread
across
all of the cluster's resources.)

Mingda,


        There is one more things that you can do without the need to
reload
your data:

        -- Enlarge the buffercache memory budget to 8GB so that the
datasets
can fit into the buffer cache:
            "storage.buffercache.size": 536870912
            ->
            "storage.buffercache.size": 8589934592

        You don't need to reload data but only need to restart the
AsterixDB
instance.
        Thanks!

Dear Yingyi,

Thanks for your suggestion. I have reset the AsterixDB and retest

AsterixDB

using new environment on 100G, 10G. The efficiency for all the tests

(good

and bad order) have been all improved to twice speed.

I will finish all the tests and update the result later.

Bests,
Mingda

Hi Mingda,


        I think that in your setting, a better configuration for

AsterixDB

might be to use 64 partitions, i.e., 4 cores *16.


        1. To achieve that, you have to have 4 iodevices on each NC,

e.g.:

            iodevices=/home/clash/asterixStorage/asterixdb5/red16


            -->

            iodevices=/home/clash/asterix
Storage/asterixdb5/red16-1,
iodevices=/home/clash/asterixStorage/asterixdb5/red16-2,
iodevices=/home/clash/asterixStorage/asterixdb5/red16-3,
iodevices=/home/clash/asterixStorage/asterixdb5/red16-4

        2. Assume you have 64 partitions, 31.01G/64 ~= 0.5G.  That
means

you'd

better have 512MB memory budget for each joiner so as to make the

join

memory-resident.


            To achieve that,  in the cc section in the cc.conf, you

could

add:


            compiler.joinmemory=536870912

        3. For the JVM setting, 1024MB is too small for the NC.
            In the shared NC section in cc.conf, you can add:
            jvm.args=-Xmx16G

        4. For Pig and Hive, you can set the maximum mapper/reducer

numbers

in

the MapReduce configuration, e.g., at most 4 mappers per machine and

at

most 4 reducers per machine.


        5. I'm not super-familiar with hyper threading, but it might

be

worth

trying 8 partitions per machine, i.e., 128 partitions in total.

        To validate if the new settings work, you can go to the

admin/cluster

page to double check.

        Pls keep us updated and let us know if you run into any
issue.
        Thanks!

Yingyi

2.Catalog_return:2.28G

catalog_sales:31.01G

inventory:8.63G

3.As for Pig and Hive, I always use the default configuration. I

didn't

set


the partition things for them. And for Spark, we use 200

partitions,

which
may be improved and just not bad. For AsterixDB, I also set the

cluster

using default value of partition and JVM things (I didn't manually


set


these parameters).

Mingda,


        1. Can you paste the returned JSON of http://<master

node>:19002/admin/cluster at your side? (Pls replace <master

node>

with

the

actual master node name or IP)

        2. Can you list the individual size of each dataset
involved

in

the
query, e.g., catalog_returns, catalog_sales, and inventory?  (I

assume


100GB is the overall size?)


        3. Do Spark/Hive/Pig saturate all CPUs on all machines,

i.e.,

how

many

partitions are running on each machine?  (It seems that your

AsterixDB

configuration wouldn't saturate all CPUs for queries --- in the


current


AsterixDB master, the computation parallelism is set to be the


same


as

the

storage parallelism (i.e., the number of iodevices on each NC).

I've

submitted a new patch that allow flexible computation
parallelism,
which

should be able to get merged into master very soon.)

        Thanks!

Best,
Yingyi

Oh, sure. When we test the 100G multiple join, we find

is

slower

than Spark (but still faster than Pig and Hive).

I can share with you the both plots: 1-10G.eps and 1-100G.eps.

(We

will

only use 1-10G.eps in our paper).

And thanks for Ian's advice:* The dev list generally strips

attachments.

Maybe you can just put the config inline? Or link to a
pastebin/gist?*


I know why you can't see the attachments. So I move the plots
