I have a for look that is inserting a row on a table, after save I call a
function with go to start a go routine where inside I query other table,
process some data and then save the same table that called the go routine. I
get this on the first read.
my code is like
```
for _, myDto := range myDtos {
handler.save(myDto)
}
```
handler save looks like
```
session := getSession(ctx)
q = myTable.InsertQuery(session).BindStruct(myDto)
defer q.Release()
err = q.ExecRelease()
go saveEventHandler.publish(&myEvent{
dto: myDto
}
```
saveHandler
```
session := getSession(ctx)
query :=
session.Query(repo.myMetaDataTable.SelectAll()).PageSize(200).PageState([]byte{})
defer query.Release()
metadatas := []*venueModels.VenueMetadata{}
iter := query.Iter()
```
iter := query.Iter() triggers the issue, have this behavior all the time.
the handler save method first store the data on the table and start the go
routine, if after handler.save(myDto) I add a time.Sleep(1 * time.Second) error
goes away.
