[BUG] IC14无法用Cypher执行

失敗しているクエリは ic14.cypher です。まずそれを再現し、GraphRowCountHandler.java の 225 行目を調べてください。そこでは、stack trace が GraphLogicalUnfold の行数推定の失敗を報告しています。GraphPlanner.java と QueryCache.java を通じてプランニングを追跡してください。IC14 Cypher クエリが LOGICAL_PLAN_BUILD_FAILED なしで実行されれば完了です。

执行查询文件: ic14.cypher

查询内容:
MATCH all ShortestPath((person1:PERSON { id: 32985348834605L })-[path:KNOWS0..]-(person2:PERSON { id: 4398046511592L }))
WITH path, gs.function.relationships(path) as rels_in_path
UNWIND rels_in_path as rel
WITH path, gs.function.startNode(rel) as rel0, gs.function.endNode(rel) as rel1
OPTIONAL MATCH (rel0:PERSON)<-[:HASCREATOR]-(n)-[:REPLYOF]-(m)-[:HASCREATOR]->(rel1:PERSON)
With path,
CASE WHEN labels(m) = labels(n) OR n is null THEN 0 ELSE 1 END as ra,
CASE WHEN labels(m) <> labels(n) OR n is null THEN 0 ELSE 1 END as rb
With path, gs.function.nodes(path) as nodes_in_path, SUM(ra) AS weight1Count, SUM(rb) as weight2Count
UNWIND nodes_in_path as node
WITH path, COLLECT(node.id) as personIdsInPath, weight1Count, weight2Count
RETURN personIdsInPath, (weight1Count + gs.function.toFloat(weight2Count) / 2) AS pathWeight
ORDER BY pathWeight DESC;
