Subject cassandra as an email store ...
Date Fri, 29 Apr 2011 09:19:26 GMT

Previous discussions have covered cassandra not being the best at
storing large binary files and it makes more sense to store pointers
to the files in cassandra and for the files themselves to be stored on
a local file system or some other entity like amazon s3, etc.

if i wanted to funnel all emails received by an SMTP server into
cassandra, would this be bad?  my initial thought was each recipient
email address is a key, and each message is a new column {
timestamp:message } with the thought being, if there are attachments,
these would be saved to a file system (or maybe even hdfs) and
referenced in a seperate column.

cassandra fit for the task?  anyone done this already?  i quickly
threw together a POC last night with pycassa and python smptd ... so i
know it's possible....
