>all SQL clustering Uh that's simply not true? VoltDB, for instance, easily and natively supports sharding. SQL Server's AlwaysOn system (despite being failover clustering) is incredibly simple to setup and is transparent to clients. The OP is asking about a problem with only 1M records. Unless they're huge records or something, no one should be discussing such a small number of records as a performance limit.
