Can you please let me know the datasize that you are using to test and how you have loaded the data into Carbon Table. In the below code the query model is created and the results are returned in chunks. So if you let me know the above details will try to see where it is going wrong. Also  can you please add below properties in your carbon.properties and let me know the statistics

"carbon.enable.vector.reader", "true"
"enable.unsafe.sort", "true"
"enable.query.statistics", "true"
