Number of Cached Values determines the number of values the Integration Service caches at one time. When Number of Cached Values is greater than zero, the Integration Service caches the configured number of values and updates the current value each time it caches values.
When multiple sessions use the same reusable Sequence Generator transformation at the same time, there might be multiple instances of the Sequence Generator transformation. To avoid generating the same values for each session, reserve a range of sequence values for each session by configuring Number of Cached Values.
To increase performance when running a session on a grid, increase the number of cached values for the Sequence Generator transformation. This reduces the communication required between the master and worker DTM processes and the repository.
