Hi, According to https://www.monetdb.org/Documentation/Cookbooks/SQLrecipes/DistributedQueryP... It is said that, "Queries involving remote tables are automatically split into subqueries by the master database and executed on remote databases.". I think this scenario: I have 3 server, one master server and two worker servers. I have 2 tables, A (big one, a fact table) and B (small one, a dimension table). A is a merge table of 2 remote tables. The remote table exist in two worker servers. B is a dimension table, that I'm not sure, on which server, I should place it on. And I will do queries, that join A and B. On which server, I should place table B to achieve distributed query processing? Is table B should be replicated on all remote table? Thanks, -Aris
