Consider using a replicated table when:

- The table size on disk is less than 2 GB, regardless of the number of rows. To find the size of a table, you can use the [DBCC PDW_SHOWSPACEUSED](https://docs.microsoft.com/sql/t-sql/database-console-commands/dbcc-pdw-showspaceused-transact-sql) command: `DBCC PDW_SHOWSPACEUSED('ReplTableCandidate')`.

- The table is used in joins that would otherwise require data movem'nt. When joining tables that are not distributed on the same column, such as a hash-distributed table to a round-robin table, data movement is required to complete the query. If one of the tables is small, consider a replicated table. We recommend using replicated tables instead of round-robin tables in most cases. To view data movement operations in query plans, use [sys.dm_pdw_request_steps](https://docs.microsoft.com/sql/relational-databases/system-dynamic-management-views/sys-dm-pdw-request-steps-transact-sql). The BroadcastMoveOperation is the typical data movement operation that can be eliminated by using a replicated table.
