Re: Storing videos in cassandra

[vvshvv]

I have a requirement to store images of different sizes somewhere and display images of same size in grid (up to 50), and looking at Pithos architecture, relatively large files will be divided in small chunks and they will not be combined into one file quickly.

I haven't had the chance to test Pithos but from an architectural view it
MUST be slower than a haystack-like architecture (
https://code.facebook.com/posts/685565858139515/needle-in-a-haystack-efficient-storage-of-billions-of-photos/).
This is why we decided to move to SeaweedFS (

(master server) but it is so slim and well designed that you really need to

designed for simplicity + speed.
If you need more functionality, like authentication, permission management,

choice. Actually there are really a lot of solutions for a Blob-Store. Some

 Do they just use references to the video files in the form of URL's and

There is a project Pithos that stores blob in Cassandra and exposes them
via S3 compatible API:

IIRC, I watched a presentation where they said Netflix store almost
everything in C* *except* video content and payment stuff.

That was 1-2 years ago. Not sure if it's still the case.

URI comes in pretty handy ; 

video://videoprovider:codecSomething:myConverter:videoId 


Or XRI but what Michael said.

Re: Storing videos in cassandra

[Michael Shuler]

Forward thinking, I would also suggest not storing the full URL, just
the video ID of some sort. The application code can create the URL as
needed, using the ID. If the full URL is stored in Cassandra and some
day in the future, the video file storage system needs to be changed,
this would require updating all the records. One could also use multiple
storage systems, based on if the ID has some characteristic..

Re: Storing videos in cassandra

[Paulo Motta]

For the record, there is an interesting use case of globo.com using
Cassandra to store video payload and stream live video at scale (in
particular, the FIFA World Cup + Olympics), but it's a pretty
non-conventional/advanced use case:

Re: Storing videos in cassandra

[Benjamin Roth]

Some time ago, I stumbled across this:
https://github.com/chrislusf/seaweedfs
It is an open source implementation of Facebooks Haystack design. Have no
experience yet but we will evaluate it as a blob-store to replace our
Mogile-FS installation which stores over one billion images. From my point
of view it looks very promising and probably much more resource-friendly
for this use case.

Maybe that helps ...

Re: Storing videos in cassandra

While Cassandra *can* be used this way, I don’t recommend it.  It’s going to be 
far cheaper and easier to maintain to store data in an Object store like S3, 
like Oskar recommended.

Re: Storing videos in cassandra

[Jon Haddad]

Think about it like this.  You just started using Cassandra for the first time. 
 You have a question, you find there’s a mailing list, and you ask.  You have 
zero experience with the DB and are an outsider to a community.  You ask 
anyways, because it’s where the Apache website says to go.  You get back 2 
sarcastic responses which aren’t helpful at all.  You, Ali, are the first 
contact with the community and it's a negative one.  Your joke, however funny 
it is, excludes someone who isn’t on the inside.  They don’t get the elbow to 
the ribs, haha, we’re just having fun, they get the “wow, all I did was ask a 
question and I got made fun of” feeling.

Everyone is a beginner, and an outsider, at some point.  Please keep that in 
mind no-one has any understanding to the intent on your jokes when all they 
have is a 2 sentence response that is obviously not meant to be helpful.

You’ve asked a lot of questions on this mailing list, and you’ve gotten help on 
a ton of beginner issues.  Making fun of someone for asking similar beginner 
questions is not cool at all.  Cut it out.

Excuse me? I did not make fun of anyone. I gave valid suggestions that are
all theoretically possible.

If it came off in a condescending way, i am genuinely sorry.

Re: Storing videos in cassandra

We store videos and files in Cassandra by chunking them into small portions and 
saving them as blobs.  As for video you could track the file byte offset of 
each chunk and request the relevant pieces when scrubbing to a particular 
portion of the video.

Another solution could be to print the raw bytes to paper, and write the
page numbers to cassandra. Playback will be challenging with this method
however, unless interns are available to transcribe the papers back to a
digital format.

The video can be written to floppy diskettes, and the serial numbers of the
diskettes can be written to cassandra.

The actual video is not stored in Cassandra. You need to use a proper origin 
like s3. 

Although you can probably store it in Cassandra, it's not a good idea.

Storing videos in cassandra

[raghavendra vutti]

 Just wanted to know How does hulu or netflix store videos in cassandra.

Do they just use references to the video files in the form of URL's and
store in the DB??
