What Is The Difference Between Classic And Coordinated Replicat? |
|
Answer» The difference between classic MODE and coordinated mode is that Replicat is multi-threaded in coordinated mode. Within a single Replicat INSTANCE, multiple threads read the trail independently and APPLY transactions in parallel. Each thread handles all of the filtering, mapping, conversion, SQL construction, and error handling for its ASSIGNED workload. A coordinator thread coordinates the transactions across threads to ACCOUNT for dependencies among the threads.
