Hi,
I am facing promlem of entering many data into the Google App
engine database as its taking more then 30 sec time limit.
PersistenceManager pm = PMF.get().getPersistenceManager();
for(;;)
{
EnterData data = new EnterData(key,value,new Text(totaData));//
EnterData is my class Entity
pm.makePersistent(data);
}
How can i use the Tasks/Queues in this scenario
You could try using bulk put rather than making a datastore call for
every iteration.
You can also do many store operations in parallel if you use Twig like
this:
for (...)
{
datastore.store().instance(data).later();
}
this is an non-blocking async call that returns immediately and lets
you run all your operations in parallel.
Otherwise, to use task queues I would recommend using the Deferred
library to chain tasks:
