Titan: A High-Performance Remote Sensing Database

There are two major challenges for a high-performance remote-sensing database. First, it must provide low-latency retrieval of very large volumes of spatio-temporaldata. This requires effective declustering and placement of a multidimensional dataset onto a large disk farm. Second, the order of magnitude reduction in data-size due to postprocessing makes it imperative, from a performance perspective, that the postprocessing be done on the machine that holds the data. This requires careful coordination of computation and data retrieval. This paper describes the design, implementation and evaluation of Titan, a parallel shared-nothing database designed for handling remotesensing data. The computational platform for Titan is a 16-processor IBM SP-2 with four fast disks attached to each processor. Titanis currently operational and contains about 24 GBof AVHRRdata from the NOAA-7 satellite. The experimental results show that Titan provides good performance for global queries and interactiv...
