+SQL Analytics implements a replicated table by maintaining a master version of the table. It copies the master version to the first distribution database on each Compute node. When there is a change, SQL Analytics first updates the master version, then it rebuilds the tables on each Compute node. A rebuild of a replicated table includes copying the table to each Compute node and then building the indexes. For example, a replicated table on a DW2000c has 5 copies of the data. A master copy and a full copy on each Compute node. All data is stored in distribution databases. SQL Analytics uses this model to support faster data modification statements and flexible scaling operations.
