I am currently building a social network application where one of the
important features is a feed / wall (Something similar to the Facebook
wall). We will have several feeds, one for each profile and one for
each group and so on. I have looked into using Cassandra for storing
this, but I am not sure I am on the right track regarding my "schema".
My thoughs was that the schema would be similar to this
Feed [SuperColumn]
- Row [user id as identifier]
[Columns]
- type
- timestamp
- message
- url
Each user would have his own feed super column and store all feed
items related to him in this super column. I am not sure this is the
best idea, since it creates an insane amount of writes whenever
someone writes to their wall (this will have to write the feed of all
his friends). Also I read in this thread http://www.mail-archive.com/[email protected]/msg00360.html
that super columns are not suited for > 60k rows in a super column.
What would be the optimal way of storing a set of feeds in cassandra?
Thanks
Kristian
