Hi, So i'm playing around with the map reduce and just faced this problem (more of a unknown actually)
The one i ran takes about 40GB worth of entities and deletes them (i'm not using the datastore admin since i actually need to speed the process by sharding more and increasing the process rate). Unfortunately, reaching the end 2 shards faced some validation problems and the task queues were just too much pushed back and i just aborted the map reduce. I'm sending all the delete operations (i know they are expensive) thru the Mutation Pool api that the MapReduce library provides. 1.) as i understand it (looking at the code) the mutation pool is flushed (actual db operation) until a max of entities (or size) is reached, this is per shard right? 2.) if the previous is correct, i should have about 90% of my deletes completed. Anyone know when these are actually accomplished? (i know it takes some time to reflect the actual change in your entity/datastore due to the nature of deletes) but just wondering if i should expect an approximate time. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
