Research on storage and retrieval of massive GPS and video surveillance data in cloud environment

In order to solve the problem of storage and management efficiency of massive urban monitoring data, HDFS distributed file system is used to store video unstructured data, HBase attribute information table is researched and designed, HBase distributed database is used to store attribute information, HBase global retrieval information row key and MapReduce workflow are studied, retrieval is constructed, and video monitoring data retrieval is realized. Finally, based on the research of unstructured data retrieval technology and distributed data processing framework, we get the massive urban monitoring data storage and retrieval scheme.
