Marcio Silva commented on ACCUMULO-776:
---------------------------------------
It's described briefly on page 374 of Lars George's [HBase: The Definitive
Guide|http://www.hbasebook.com/] and the schema used for inbox search is also
described in this slide deck from QCon London [HBase @
Facebook|http://qconlondon.com/dl/qcon-london-2011/slides/KannanMuthukkaruppan_HBaseFacebook.pdf]
The basic idea is they build per-user search indices in a single HBase row
using the version to store the message ids.
> TimestampFilter should serialize start and end as longs in the IteratorSetting

>
> Although the TimestampFilter supports using longs to set the start or end
> timestamp, it formats them as strings using SimpleDateFormat when storing or
> retrieving them in the IteratorSetting.
> This results in exceptions when the timestamps being used aren't able to be
> formatted as _yyyyMMddHHmmssz_. For example, try
> {{setEnd(253402300800001,true)}}
> Instead, {{setStart()}} and {{setEnd()}} could just as easily use
> {{String.valueOf(long i)}} to store the values, and {{init()}} could retrieve
> them using {{Long.valueOf(String s)}}.
