group by - Aggregate functions on windows azure storage tables -


i have windows azure storage table in storing more 1000k+ rows(entities). wants perform few aggregate functions on table counting on specific column specific condition, average, total, min, max , group by (as in normal sql). how can in windows azure storage tables?

the way pretty pull down entities , run aggregates on them in memory.

if have keep information date store these aggregates in place , update them every time new entity added. instance average sum/count can have table item stores current sum , count , when add new entity update sum , count values.

make sure use optimistic concurrency can catch race conditions etc. if table entities share same partition key can operation on same transaction.
