As mentioned earlier, the system must also address the challenges posed by the distribution of data.In our case, the optimizer will decide which algorithm to use to connect S1 and S3. For example, a connection algorithm might import the movie name from S1 to S3 in a pipelined format, or it might cache the results fir
