Deprecated feature: The partitioning facility (WPF) feature is deprecated. You can configure partitioning with WebSphere eXtreme Scale.


Slave multiple reader and Master single writer pattern

The optimal application for this pattern requires a single writer for an application partition at a time for high write performance. This writer uses a write through cache for database access. As long as there are no external applications modifying the database then the writer can cache very aggressively and virtually eliminate queries against the database. The read load on a given partition, however, would be very high. The application also has a requirement to not allow heavy read activity to slow down the writer. It is also permissible for the reads to be slightly stale. You also want to be able to distribute the readers for a partition across multiple cluster members to spread the system load.
