When using the single-row schema, each user session maps to a single database row. This is WebSphere's default configuration for persistent session management. With this setup, there are hard limits to the amount of user-defined, application-specific data that WAS can access.

When using the multi-row schema, each user session maps to multiple database rows, with each session attribute mapping to a database row.

In addition to allowing larger session records, using a multi-row schema can yield performance benefits.
