Title: Framework for GeoSpatial Query Processing by Integrating Cassandra with Hadoop
Abstract: Now-a-days we are moving towards digitization and making all our devices such as sensors, cameras connected to Internet producing bigdata. This bigdata has variety of data and has paved the way to the emergence of  NoSQL databases, like Cassandra for achieving scalability and availability. Hadoop framework has been developed for storing and processing distributed data. In this work we mainly investigated on storage and retrieval of geospatial data by integrating Hadoop and Cassandra using Prefix-based partitioning and Cassandra’s default partitioning algorithm i.e Murmur3partitioner .techniques. Geohash value is generated, that acts as a partition key and also helps in effective search. Hence the time taken for retrieving data is optimized.  When user requests for Spatial queries like finding nearest locations , searching in Cassandra database starts  using both partitioning techniques. A comparison on query response time is made so as to verify which method is more effective. Results showed that Prefix-based partitioning technique  is efficient than Murmur3 partitioning technique
