| <div class="block">DeMuxExchange is opposite of MuxExchange. It is used when the sender has overhead that is proportional to the |
| number of receivers. DeMuxExchange is run one instance per Drillbit endpoint which collects and distributes data |
| belonging to local receiving fragments running on the same Drillbit. |
| |
| Example: |
| On a 3 node cluster, if the sender has 10 receivers on each node each sender requires 30 buffers. By inserting |
| DeMuxExchange, we create one receiver per node which means total of 3 receivers for each sender. If the number of |
| senders is 10, we use 10*3 buffers instead of 10*30. DeMuxExchange has a overhead of buffer space that is equal to |
| number of local receivers. In this case each DeMuxExchange needs 10 buffers, so total of 3*10 buffers.</div> |
