I'm currently storing entities of a particular kind (e.g. TrafficHits). I would like to begin removing older entities (e.g. older than a month), but would like to calculate summary statistics on these records before deleting them.
What's the recommended approach for this (I'm using Java JDO)? 1) Perform a query to retrieve entities older than a month. Loop through records and calculate stats. Delete entities using a delete query with same where clause. This seems somewhat inefficient. 2) A mapreduce job? Any help would be appreciated.
