Hello,
i try to delete all records in a datastore, a simple table with a time
serie of int values
there are more than 25000 entries
when i do :
homedata_query = Homedata.all()
homedatas = homedata_query.fetch(300)
db.delete(homedatas)
if the fetch count is greater then 300 i receive a timeout
so i have to repeat this a huge number of time
it did take me about 20 min to do that
and it cost 2.38 CPU hours because the CPU sec used /sec was up to 8
This is not useable, i want to store (and be able to delete) more than
100k entries,
deleting 300 by 300 would take more than one hour to complete and cost
8h of cpu
what is the trick to instant delete, like the -c option in the App
Engine SDK ?
btw can someone explain how the cpu sec used /sec are computed
