摘要
Historical analysis of query patterns is used to discover relationships between data sets. These relationships are used to make optimal decisions about where to place data in a globally distributed environment in which locality of data is an important factor in providing good query performance. A mixed integer programming model is used to solve a constraint based system which balances the need to have data kept local with other data and the cost of replicating data across a low -bandwidth network.
