+# Nebula Algorithm test
+
+## Data preparation
+
+1. Install Nebula Graph 3.0.0
+    * cluster info:
+    
+    `3 metad, 3 graphd, 3 storaged`
+    
+    * space info:
+    
+    |Name	    |Partition Number|Replica Factor|Charset|Vid Type|
+    |-----------|----------------|--------------|-------|--------|
+    |algo_space	|       100	     |     1	    |  uft8	|  int64 |
+
+2. Put LDBC sf100 dataset to HDFS: /ldbc/sf100
+
+    We use Nebula Exchange to import ldbc sf100 dataset into Nebula, importing details see: https://github.com/vesoft-inc/nebula-exchange/tree/master/bench
+    
+
+## Test algorithms with HDFS datasource and HDFS data sink
+We use LDBC's `forum_hasMember_person` edge dataset to test the algorithms.

+# Test algorithms with Nebula datasource and Nebula data sink
+We use Nebula's `HAS_MEMBER` edge type to test the algorithms, and the result is writen into new tag.
