Types of Edges
There are four types of edges, three of them have some internal buffer, you can select among edges by clicking the item and clicking some of the presented types.
Types of edges can be set to one of the following:
Direct edge. This type of edge has a buffer in memory, what makes possible faster data flow. This is the edge default type.
Buffered edge. This type of edge has also a buffer in memory, but, if necessary, it can store data on disk as well. Thus the buffer size is unlimited. It has two buffers, for reading and writing.
Direct fast propagate edge. This is an alternative implementation of the Direct edge. However, this edge has no buffer and it also makes possible fast data flow. It sends each data record to the end of this edge as soon as the edge receives it.
Phase connection edge. This edge cannot be selected, it is created automatically between two components with different phase numbers.
If you do not want to specify some explicit edge type, you can let selected the default option: Detect default. In such a case, Clover itself decides which edge type should be used.
