Yes, based on your test script, the algorithm outputs results every time the
graph changes. Since the default `windowSize` is `1` and your script does not
override it, each vertex/edge insertion triggers the WCC computation.
The relevant configuration is defined as:
```java
public static final ConfigKey GEAFLOW_DSL_WINDOW_SIZE = ConfigKeys
.key("geaflow.dsl.window.size")
.defaultValue(1L)
.description("Window size, -1 represents the full window.");
```
### Solution
To ensure the algorithm runs **only once** after the entire graph is
constructed, add this line to your script:
```sql
SET geaflow.dsl.window.size = -1;
```
### Example
```sql
SET geaflow.dsl.window.size = -1; -- Run WCC once after graph fully loaded
```
### Explanation
- **`geaflow.dsl.window.size = 1`** (default): Executes the algorithm after
every single mutation (vertex/edge insertion).
- **`geaflow.dsl.window.size = -1`**: Delays execution until all mutations
in the current batch are applied, then runs the algorithm once and outputs the
final result.
This change eliminates duplicate intermediate outputs and ensures only the
final connected components are written to `cc_geaflow_test`.
