Eric Charles commented on MAILBOX-44:
-------------------------------------

... and Ioan, don't forget to delete the apache-extra repo (http://code.google.com/a/apache-extras.org/p/mailbox-hdfs/)
or to clearly indicate on the project home page that the code is now part of the official
apache james mailbox repo (if you want to keep the hg repo as reminder :)

Thx again

Eric

> Context: The mailbox subproject (http://james.apache.org/mailbox/) supports maildir,
SQL database (via JPA) and Java Content Repository (JCR) as technology for mail storage. This
flexibility is achieved thanks to a API design that abstracts mail storage from the mail protocols.
> Task: We need to implement mailbox storage as a distributed system on top of Hadoop HDFS.
The James mailbox API will be used. A first step is to design how to interact with Hadoop
(native api, gora incubator at apache,...) and deal with specific performance questions related
to mail loading/parsing in a distributed system (use map/reduce or not, use existing local
lucene indexes for search,...). The second step is to implement the HDFS mailbox (maildir
mailbox is similar because is stores mails as a file and can be an inspiration). A single
James server will still be deployed because we don't have any distributed UID generation.
