What changes were proposed in this pull request?
This pull request introduces a new graph algorithm: Path Cycle Detection. This algorithm allows users to find all simple cycles within a specified path length in the graph.
The main changes include:
PathCycleDetection.java
: Implemented the core logic for the cycle detection algorithm.BuildInSqlFunctionTable.java
to make the new algorithm callable via GQL.gql_algorithm_009.sql
for the GQL test case.testAlgorithm_009()
inGQLAlgorithmTest.java
.gql_algorithm_009.txt
file with expected results.How was this PR tested?
The correctness of the algorithm was verified by running the newly added unit test. The test command is as follows:
mvn test -pl geaflow-dsl/geaflow-dsl-runtime -Dtest=com.antgroup.geaflow.dsl.runtime.query.GQLAlgorithmTest#testAlgorithm_009
