Projection hash buffer

WebProjection Based on Hashing ! Partitioning phase: Read R using one input buffer. For each tuple, discard unwanted fields, apply hash function h1 to choose one of B-1 output buffers. " Result is B-1 partitions (of tuples with no unwanted fields). 2 tuples from different partitions guaranteed to be distinct. ! WebThe variation in size of geodesic buffers shows how the map projection is distorted, because each buffer would appear identical in size on a globe. The same results, though exaggerated, are shown in the 3,000 km buffer graphic. With any type of analysis of distance on a global scale, geodesic buffers should be used because (again) they more ...

WebSince we need to perform 10 selections, the cost is 3*10=30 and the result has 100 tuples. (c) Join the result with Item using the unclustered hash index on Name. Since Name is a key, each hash brings 1 tuple and costs 1.2 (the cost of the hash) + 1 (the cost of retrieving the matching tuple) = 2.2 I/Os.
