If the Integration Service encounters a deadlock when it tries to write to a target, the deadlock only affects targets in the same target connection group. The Integration Service still writes to targets in other target connection groups.

Encountering deadlocks can slow session performance. To improve session performance, you can increase the number of target connection groups the Integration Service uses to write to the targets in a session. To use a different target connection group for each target in a session, use a different database connection name for each target instance. You can specify the same connection information for each connection name.
