Subject Re: Storing videos in cassandra
Date Sun, 20 Nov 2016 10:52:43 GMT
<div dir="ltr">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.<br>

This is why we decided to move to SeaweedFS (<a href="https://github.com/chrislusf/seaweedfs">https://github.com/chrislusf/seaweedfs</a>).
It still has a central component (master server) but it is so slim and well designed that
you really need to hit a Facebook-like scale to push it to the limits. Haystack is purely
designed for simplicity + speed.<div>If you need more functionality, like authentication,
permission management, multi-tenancy, whatever, it probably will not be the architecture of
your choice. Actually there are really a lot of solutions for a Blob-Store. Some use Cassandra,
many of them have different approaches, every one with its own pros and cons for certain use
cases.</div></div><div class="gmail_extra"><br><div class="gmail_quote">2016-11-20
