Hey all,
I'm currently hitting the instance soft memory limit of 256MB by doing
this...
q := datastore.NewQuery("MetaPLBStruct").Limit(500)
for t := q.Run(c); ; {
var x MetaLBStruct
key, err := t.Next(&x)
if err == datastore.Done {
break
}
// Do something here
}
Yet I don't run out of memory if I do this...
var lbEnts []MetaLBStruct
lbKeys, err := datastore.NewQuery("MetaPLBStruct").Limit(500).GetAll(c,
&lbEnts)
for _, v := range lbEnts {
// Do something here
}
I wrote the routine the first way because I have lots entities to get, much
greater then 500 and I wanted to iterate all of them. I've previously hit
a limit of 512(?) entities when using GetAll().
So, what am I doing wrong? I see python has some kind of batch size that
is missing from Go, would this help?
Is there anyway I can see how much memory my instance is using? I suspect
that each .Next() call is taking up quite a bit of memory, perhaps I can
early out if I know I'm getting close to the limit?
Many thanks,
Ash.
