Subject [jira] [Commented] (ACCUMULO-776) TimestampFilter should serialize start and end as longs in the IteratorSetting
Date Mon, 05 Nov 2012 21:34:12 GMT


Keith Turner commented on ACCUMULO-776:

bq. Yikes, does that mean we'd have to include timestamp format conversion for configured
TimestampFilters in our upgrade from 1.4 to 1.5?
This could be done in the TimestampFilter code that reads the config rather than as part of
the upgrade process.  I think we can identify the old persistent format because it ends with
alpha chars and distinguish that from the new format which all numeric chars?  Unless there
is a completely numeric timezone?  

bq.   Did this ticket get opened because someone needed a year >= 10000?
I suppose any long is valid in the timestamp, so the filter should probably handle it.

> 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)}}.
