Ongoing Tasks - General Info

Ongoing tasks are work tasks defined for the database.
Once defined, these tasks are ongoing, meaning that they will do the defined work for any data change in the database.
Each task has a responsible node from the Database Group nodes, this node will actually perform the defined task work.
The available ongoing tasks are:
