Components of Parallel DSI

Learn about the components of parallel DSI.

Parallel DSI Components
Figure 4-3 shows the components of parallel D S I. In the replicate Replication Server, messages are stored in the outbound stable queue, and then sent to the D S I scheduler thread, shown as D S I dash S in this figure. The messages in the D S I scheduler are then distributed to the D S I executor threads that send the messages to the replicate data server.

DSI Scheduler Thread
The DSI scheduler thread (DSI-S) collects small transactions into groups by commit order.
DSI Executor Threads
The DSI executor threads (DSI-E) map functions to function strings and execute the transactions on the replicate database.
