是否可以运行使用 AWS 密钥空间作为存储后端的 JanusGraph Docker 容器？
我尝试使用Janus Graphscassandra-es模板配置密钥空间。如果我运行以下docker-compose.ymlJanusGraph 会记录异常，并且所有查询都会返回ScriptEvaluationError: gremlin-groovy is not an available GremlinScriptEngine'。也许无法建立与密钥空间的连接？

目前似乎无法将 JanusGraph 连接到 AWS 密钥空间。
为了与 AWS 密钥空间连接，需要启用 SSL 通信。也就是说，需要为 JanusGraph 配置以下设置：
'storage.cql.ssl.truststore.location=<location>'
'storage.cql.ssl.truststore.password=<truststorepw>'
'storage.cql.ssl.enabled=true'
不幸的是，即使在启用SSL之后，JanusGraph也会在启动时抛出异常(相关(：
java.lang.IllegalArgumentException: Unrecognized partitioner: com.amazonaws.cassandra.DefaultPartitioner
这似乎是由于在JanusGraphs的CQLStoreManager中显式检查分区程序名称引起的。总而言之，AWS Keyspaces 使用自定义分区程序，而 JanusGraph 不支持该分区程序。
