Hi Andrew,
I did try with the Iterator implementation using iterator.hasNext() (you can see that its commented in the code i shared) but the performance is only slightly higher (hence gave the range 10-100 keys per second) Do you want me to try to use a cursor explicitly instead of using an iterator. I need to go through all the keys and perform the computation. Regards Anand Vijai -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
